Serious Help and Advice Need

It's been so long since I have been on here and something big has happened for me to have come back. I had a live-in-aide who was my best friend, he usually is really sweet to me, bu then this horrific day happened. He was yelling at me in my face and telling me why do I put on act to get special services and how he also does the cleaning while he is sick and why he shouldn't have to put up with my criticizing mother, while yelling he also poked me in the chest. When he stopped I was upset, so having a ps3 and big TV he was about to sit down to play a game, but I unplug it and walked away to my room. I was just going to stay in my room as usual, but he came and took my cellphone away. I got upset and followed him out of my room to get my phone back. I kept telling him to give my phone back but he didn't. We started pushing at shoulder to shoulder, I tried reaching into his pocket but I got the wrong one. Then we kept pushing at shoulder to shoulder again. Getting frustrated I picked up some scissors and swang them around to scare him, but I accidentally stabbed him. I dropped the scissors and started crying as I saw the blood and I told him I didn't mean to. There was so much blood and I thought he was going to die. He immediately gave me my phone to call the ambulance, then he told me to call my mom and I did. Then he called his dad and as he did he told me to put pressure on his arm where he wrapped paper towels around his arm. We started walking out of the apartment as I put pressure on his arm to meet the medics by the elevator. As soon the police and medics came up they separated me from him and I was crying completely worried. I told the police the truth, the detective the truth, he didn't press charges on me, but I was sent to a hospital to see a psychatrist. They cleared me in time to find out I was evicted from my apartment. He doesn't want nothing to do with me, but I am trying to be civil. He told me how he walked back to our apartment in rags and had to sleep in the laundry room. He has posted on facebook on how he got stabbed. He told me he would only tell his close friends and told me he would tell my friends a random crime. But I have two close friends that I want to tell the truth, but I told them lies over the phone. I want to tell them the truth face to face. Should I tell my friends what's really going on or not?
