Here is my story and what should do I to save myself?

Last Friday I pulled down into the deans office by two deans, and the principle. They did not tell me what was going on, as we got to an unknown office they searched without telling why I was being searched, they didn't find anything incriminating on me, they then confiscated my phone, and asked me if I knew about two of my friends who were selling drugs in school to students, the drug was 25c nbome a research chemical which upon later research I found was not scheduled by the DEA making it legal. They trapped me in this small room and asked me to tell them "everything" confused I said "what is going on?" they said that somebody said that I was involved in the sale of this "25c" drug to students I denied all accusations and told them the only things I knew about it was a conversation I overheard in my chemistry class which 3 students were taking about the sale of the drug and that they would take it at lunch, I then said that I was aware that two of friends lets call them M and L might have been involved in the sale of this drug. I also said that L's girlfriend who usually associates any activity M and L are involved in with me, I mentioned that L and I have gotten in a fight(argument) a while back and that to destroy my image told his girl friend a bunch of rumors about me, I wrote all this down on a signed statement I was forced to write, I was then locked in this small room for another 1 and half until the deans came to talk to me again, they told me that other students were saying I was involved in this sale of this drug, which I wasn't, I continued to deny any accusations of such. I was then periodically visited by different school officials who asked me the same questions repeatedly and tried to pressure me into an admission of guilt, I continued to tell my side of the story and said I was completely innocent. I was then left in this room for another 4 hours which I was then allowed to go to the bathroom after being denied the ability to earlier. I asked if I could call my parents to let them know what was going on, they then said "we'll talk to them" I said "No i want to talk to them" they then yelled saying they would do so first. I saw through the small narrow window on the door the other students who were involved being called down, searched and interviewed after me. They then searched L and found a couple of tabs of the substance on him and suspended him for 10 days, I knew M had money and drugs on him at school, but I am unsure if those were discovered. After the other kids were released 3 deans, the principle, and the Assistant principle of student services trapped me and cornered me in my room. They said that One of the students (L and M) said that I ordered this drug online for them and sent it to L's house, I denied such accusations. I told them that if they cannot find any hard evidence against me how could they accuse me and punish me for distribution of drugs, they then said that the other students word was enough for grounds of suspension. I told them I was a quiet kid who did not have many friends who just kept to myself and never did anything bad, and my record at school supported this. I then got emotional when i forced to explain how my friends had bullied me and abused me mentally, and how I stopped hanging out with them because of this, I started to tear up as I explained i never been a liked kid at school because people didn't think i was "cool" and that I could count the only friends I've ever had on two hands. One of the deans smirked and made fun of me for this statement, I am very sensitive about this because I find it very personal. They then said "so you were selling drugs to make friends?" I said "No, i never sold anything, don't put words in my mouth" they then all closed in on me and tried to force a confession out of me which I didn't give, because I was innocent, the charge against me was conspiring to distribute drugs in school to students. I said the other kids saw me as a scape goat and thought that I wouldn't tell on them, because I would be scared, they also searched my locker and threw and damaged all my belongings in my locker, they didn't find anything. They then told me I was being suspended for ten days out of school, I said "how can you punish me if you cannot prove I did anything!" they said they didn't need to prove it. The dean then called my dad and said I announced at my lunch table that I "ordered" the drugs and that they would be in soon. they then used the fact that I saw one of my friends at the gym as a potential drop off for drugs, which wasn't true I came into the gym alone and saw my friend walking out of the locker room where we talked for a bit then proceeded to work out together I, they also said that L was there for a pick up which I never saw him or contacted him that day. I also left the gym alone. They said that I picked someone up before going there I said if you check the gym cameras you will see that I got out of my car alone and walked in alone. (why would I leave someone in my car for 2:30 hours) They then told me that it was impossible that the other students would conspire against me and say that I was there distributor. Which I said it wasn't a surprise since M and L did not like me very much and may have chosen me to "take the fall for them" since they tried to do that before to me. I then told them that two kids A and B walked out to the lunch table and said to M and L "if you dont tell people that you can overdose on 25c then I'm going to kick your ass, and I will be responsible for the OD" they said "why would A and B be responsible?" I said I thought A and B may be the one supplying the drug to them, they then called my dad and told him that I admitted to ordering drugs to L's house, I yelled out "that isnt true, stop lying to my dad" another dean said to shut up they then denied me the chance to talk to my dad and hung up on him. I then told them if I was suspended then my parents would "kill me" and my sister would be fired since she is a government official, I said my life is over, that all colleges would find out that I was suspended for selling drugs and that I would never be able to find a job, I then muttered "why should i carry on with my life if my dreams are over" the dean then said dont talk about suicide I yelled at him saying "You don't know what youre doing to me, you dont understand my situation" he said he did I said "no you dont, you probably had plenty of friends who liked you, I never had one!" they then called in the counselor to say that colleges cant find out if I was suspended and that the police would not be contacted and know one would find out about this suspension, I said "why are you punishing me I never did anything!" she didnt respond. My father then showed up and asked what happened i explained everything to him He then yelled at my dean saying "How could you keep my son here for five hours without telling me?" my dean said "thats how we do things around here" my dad then said that on monday he would show up with our attorney, all the school officials seemed very nervous at this point they no longer went on the offensive they then released me and said my 10 day suspension would start on Monday with possible recommendation for expulsion, all others kids were released earlier since they confessed to the crime. I never confessed since I didn't do anything wrong. My dad said that we will get our attorney and will fight to get the suspension revoked since they had no proof against me. I also suspect that I will be expelled since my school is very strict with these kind of things. Someone tell me what I should, I don't know anyone who has been in this situation before, I'm scared that my life will be over because I was wrongly accused of this crime. My main point to argue as to why those kids all told on me was that they took my statement and showed them that I told on them where they then decided to blame me to punish me for telling on them, I don't believe in snitching but when I would be punished for your wrong doing I will no longer cover for you. My friend D later told me that M and L said that I told on everyone and not to trust me, I told them L was in the office before me so he mentioned my name and that is why I was brought down. L chose not to tell on his partner M but decided to use me as his so called "accomplice" so that he wouldn't be punished as much. Someone help me, what should my attorney do to help fight this case, and stop me from getting expelled. EDIT happy with your paragraphs now? sorry i'm very stressed and didn't focus on grammar.
