Help Much Appreciated!!

Hey everyone, I don't tend to ask for things like this but I'm needing help. I recently went to jail last Monday and was there until Thursday. The reason I was arrested was due to a PTSD trigger and to protect the baby who is 3 years old. My brother [29] has a long-standing history of domestically abusing me and my mom and has done so my entire childhood, for context I am now 19. He would beat my mom growing up and because of that I would hoard sticks or anything else I could use to keep my brother off of us which might be me going very off topic but I guess it shows just how deep this history goes? Well Monday night, he was highly intoxicated as he is now a raging alcoholic and has been abusing marijuana. Back to the point, my mom told the baby if she kept being ugly[rude] she wouldn't get to go on Vacation and said that "people need to learn actions have consequences" my brother being intoxicated kept badgering my mom and she told him not to start, he didn't listen so she threw the cookie tray on the ground, He proceeded to pick it up and threw it into the wall splitting the wall. Baby ran into my room screaming and crying, situations have happened like this before so anytime something like this happens; I lock my bedroom door, put on Tv or Music and make it loud so baby can't hear anything happening Outside of my room and I have the cats cuddle her to keep her safe and to comfort her I guess is how I would explain it? And each time I would have a screwdriver or a hammer or a mallet on standby because my brother has AK-47's, Pistols, and a Pump Barrel Shotgun and when he's drunk at night, he plays with his guns so there's genuinely a fear of him shooting us you know? But this time [on Monday] I grabbed 2 knives just in case it got to that point, brother left the house then busted through my back door and tried taking baby while intoxicated, Mom tried getting him out of my room and Stepdad was calling the cops. My brother proceeded to grab my Stepdad by his Neck, flipped him over his SHOULDER, and put him in a headlock and was choking him. The Baby jumped off my bed screaming and crying "My Chappy, My Chappy!"[She calls my stepdad chappy]. Well, when she got off the bed, my brother put the baby who is his own biological daughter in a headlock and was choking the BABY. When he put the baby in the headlock, I saw black, but I heard her screaming which is what triggered me stabbing my brother, I never went deeper than an Inch so there were no blades on the knives. I need help, Mentally I'm terrified to go back to jail and I don't think I could handle it again. It was my first time ever in any form of legal trouble and today I'm meeting with my bond Lady and CPS. I need prayers of Protection, Justice and to help me beat this case. In Jail they [cops/jail] abused me. I was in SEG completely nude with nothing but a blanket and had to go before the judge naked. They only gave me temporary clothes when I asked to go to the restroom. I wear hearing aids, and I told the nurse I needed my charger and that if she called my mom, my mom could bring the charger up. The nurse ignored my mom's calls 3x and my mom dropped off the charger, but the jail wouldn't pass it through so Wednesday and Thursday I went without my ears as they were dead, they did not give me my meds, so I went through severe withdrawals. The cops illegally raided my room and broke my dresser frame which my Ancestors altar is on my dresser, they did not give me my one free call and no one else except the judge in jail read me my Miranda rights, they dropped the knives on the ground and contaminated the evidence because the knives pierced the evidence bag. A cop also threatened my mom and has it out for her. My brother asked my mom why I stabbed him; my mother asked him who got violent first which my brother admitted too, the cop then proceeded to tell my mom that she was "On a dangerous line of threatening and tampering with a witness". I can't be within a 500-foot radius near the baby for 90 days which is as well which is hurting the baby. She got back from vacation yesterday and ran into my room looking for me and fell asleep crying because I'm not allowed home again for 90 days. Ironically when my mother got home yesterday, she went through the landlord's gate and there was a cop from my town directly sitting across the road in front of the gate which I think is more than a coincidence, The cops more than likely bugged my phone so I'm writing this all up on my laptop.

If none of this makes sense, I truly apologize. This is something traumatic for me and something that is painful and scary for me to recall and I'm asking that my family as well as myself be in your thoughts and prayers, please and thank you.
