Its hard for young kids;

Im 12, and ive been slitting my wrist for almost a year.
It all started with a guy, and he played me, and i really loved him, I know. It sounds silly, but then it turned into heaps of drama, I started doing it more and more because of him, and i told my bestfriend.
She told the school one day, and they rang my mum. Sadly i got sent to the princables office, and was crying so much. I was shattered someone else new. I was angry she told, But i sort of new.
My mum was shocked by this, and sad to. I was a bright person, but things went wrong.
I havent seen my dad and my brother for 6 years. The guy i liked, liked my bestfriend. My nan is going to die, My grandpa did die. My bestestfriend moved to queensland, The new love of my life that actually loved me and treated me well, moved to bendigo and did not tell me. I had lost my bestfriends from this, I was being abused for cutting myself, the teachers treated me like i was a baby. My family and I got evicted from my house, becuase me and my sister threw a party, and my mum hated us for a while. I ended up finding a guy this year, and i really Love him, but he hit me. He hit me becuase i hit him, it would sometimes make me cry.
But, people found out, and saw And told everyone. He then forced me to do stuff i wasnt ready for. But it was almost like i didnt have a say.
I was still being bullied in high school a little for the things i did.
But anyways this continued for a while, i was forced to counciling, To get depression test, To see a doctor. This year things have cooled down a little. but my sister moved to darwin, I was terribly sad, but it was for the best, she was a fuck up. I would cut myself wit a blade, on bot wrists, i would sit and cry on my bathroom floor.
almost hoping someone would help me, it was like i was screaming for help, but noone could hear. But at the same time, i didnt want anyone to Know anything.
Soon alot of poeple new, I went through heaps of depressing nights. Heartbreaks, forced things and un expected break downs randomly.
some times i would be laughing, and then id cry out of the blue; i thought i had bipolar, i still think i do. Alot of other things happened, but there the main things.
I have deffinately learnt in life that you should not take life for granted, espishally your family and friends.
moments ago my bestfriend told me he hates his family and friends, and is going to kill himself, i havent heard from him since, I am so worried.
He should not take life for granted,
I have now stopped cutting myself, and i am finding diferent ways to express my feelings, privately and openly.
