I Am Battling Self Harm

It all started bc I was hit in the face by my sister, my youngest sis tried to stab me with a knife and i defended myself and i got in trouble, and she threw a pot at me, chased me with a shovel, and i got hit in the face by a metal ba<x>seball bat by my best friend at the time, the guy who raped me smacked my head against the wall. I was beat by 8 guys and 6 girls to the point where i almost stabbed myself in the neck at school and i didn't leave my room for days bc of the bruises and scratches i couldn't even get out of my bed bc my ribs got kicked out of place.Travis ( my best friends bf is 8th grade) beat me for 3 years, i blamed myself and starved myself and started cutting. I was told to go kill myself and almost did but a friend stopped me, i got to the point last year where i was close to overdosing just 3 more pills, And i almost killed myself bc of my mom. I cant keep doing this i just cant. If it doesn't get better by the end of this next year ill kill myself for sure this time
