Doesnt help really

Ive been reading alot of the stories here on this wbsite and i guess i had the courage to share mine. So i guess here it is.
I am a Middle school student, being bullied for 5 years now. The first ever name i was ever called was fat and ugly. I decided, me being a good student, to tell the teacher. He made them appologize, but did that fix anything.. no.. if anything, it made it worse. Grade school finished and i was going onto Middle school. 6th grade bullying got so much more harsh on me and I started to believe it was true. I figured the only escape and release was to self harm. I did so. I stayed clean for a very long time til.. 7th grade had came along. My cousin moved in and was going to attend the same school with me. She changed me.. completely.. i got into more habits and dealing with drugs and alcohol and being pressured with self harm. This was my worse year yet. Every day, every hour, every second, i always heard something being said about me. Always false rumors floating around. I lost almost all my friends cause i changed that much. When my cousin moved back home, it took me so long to kinda figure out who i was as a real person and not who i was told i needed to be.. i was told i needed to be a bad person. Fist fights and everything. I needed to change,but i did not know how. Till i met this one person. She actually helped me with.. so much.. we can call her Sunny. She helped me find coping methods, rather than doing “drawings” on my wrist. She gave me advice and honestly, we grew. Sunny always helped me and we became best friends. She hasnt once betrayed me and honestly.. those type of people are really hard to find. I dont know what else to really say.. best advice for my ending, if you find someone like sunny, keep them in your life and never betray them. They will lead you down such a magical path that changes your life forever actually.
