Post-Traumatic stress

My 6th grade year was terrible I was in a different country for a sabbatical year because my dad was working there. So basically I start school and everything is going ok until a girl in our class tried to kill herself becuase of these two kids and they made derogatory comments about her and mocked how she spoke and spread random whisper campaigns around to make her feel bad. As soon as I noticed this I took a stand against them and spoke publicly and said that what they did was wrong. At the start they just harassed me, but then it grow to physically assualting me and stabbing me with pencils and threatening to break my arm. Then they robbed me while holding me at knife point. I tried returning to my school which was very nice with great peers, but I had at that point serious depression and after three months I tried to kill myself. I ended up at the hospital for a week and a half where I would be released after promising to attend an outpatient program. I did and am doing much better but even though I hang out with friends and am back at school I still feel like a piece of me is missing. I recently helped a girl who was going through a lot of the same stuff that I went through only she went through it in the states at my old school. It really triggered me but I worked through it. I’m basically trying to say there’s always light at the end of the tunnel just push forward.
