I just need to vent

Life for me isnt going nice right now,my friends are not here by my side anymore,my family hates me and just constantly ignoring me,my family problems became more harder than before,my sister stars hitting me,my grandma stats bodyshaming me and talking shit about me,idk maybe its my problem too because im mot that "expected child" they wanted to have,they start comparing me to others,im just 13 and nobody from any age doesn't need to be compared like me, I started self harm at the age or 11.its because of my problems,i thought it would cure me but no...its been 2 years since i havent been clean.i started gaving anxiety, depression,mental breakdowns,mommy issues,family problems day by day,i thought of ending my life so they would care about me, idk what to do anymore.my one and only friend started bullying me and framing me for no reason,my mom isnt really looking after me that often,mysister abuses me and talks shit about me,i dont have anyone by myside anymore,is it because im annoying?maybe yes or no?.i overthink why im so sensitive.
