What do I do? :'(

Hey I'm grace, I'm 14 but I guess I'm not that normal. I have severe depression, self harm and have attempted suicide 8 times (fail rite?) I have anxiety and slight skitzoidfrenia, the voices tell me to do things like break my arm.. And I try. Im anorexic and bulimic. I pull my hair out etc.. On top of that I have to deal with my friends. I have one that has been sending me suicide threats for 7 months, one that has cancer :/ and my bestfriend is anorexic and has a BMI of 14. They tried to help her when it started, but it didnt work, so I dunno what to do. It's scaring me.. She looks like she's wasting away.. Then you have my 'kinda boyfriend' (we like eachother and know, but were still single :) x )

Also, he tells me every day how he hates people who self harm.. So do I tell him? We're really good friends too..And what do I do about everything else?
