I don't know how to get my life back together... I need some guidance.

I failed a bunch of classes last year at a college and only got a few credits. I'm 19 years old and though I've tried going to school for 1-2 years, I'm still technically a freshman credits wise. I still miss my friends from that school. It's hard for me to make friends :/ This year I stopped school due to depression and feeling suicidal. Most days I couldn't get out of bed to go to school. I don't know if I was actually tired or I just didn't want to go to school. I was failing like all my classes due to me not turning in homework and doing terrible on tests. I couldn't do my homework or study because of my lack of concentration. My concentration is way off. I don't think I could read a book for 5 minutes without trouble and re-reading what I've just read. I was also feeling bad because I wasn't making friends easily. I'm extremely shy and introverted person and it takes a lot out of me to talk to a person.

I barely graduated out of high school. I don't talk to most of my high school friends because I feel like I don't have much in common with them. I'm into video games and staying in and they're into sports and going out. It took a lot of retaking classes, tutoring, and working hard on my part. It's so difficult being a full time student and having depression and anxiety.

I don't know what college I'm going to this semester. I don't have the motivation to find a new school. Well, I have one school in mind, but I'm not sure if I could take it with my condition. I might not go to school this semester and I feel shitty about it. I feel my time is wasting and I'm getting older. I've heard it gets harder getting an education when your older. I just feel so lost. I'm not making good use of my free time either, usually playing video games and going on Reddit, not hanging out with any friends. Though, I've been going through this job agency for youth and I might work at Marshall's or Gamestop for 4 weeks with pay or something. I don't think I have the energy to hold a job. I'm tired most of the day and all I want to do is sleep. Whatever lets me escape from my life, even for a little bit. I might volunteer at church or join a bible study, too. I feel my anxiety is through the roofs. I try exposing myself to people, but I still feel anxious. Does it get better? I'd like to believe so, but I think people just say that.
