How do I tell him???

Okay, here’s the deal… I have a boyfriend that loves me 2 death and cares about me and would do anythin 4 me… I have a lot of issues tho, but he stills loves me and tries 2 help me. I used 2 drink alcohol, do many bad and sick things with guyz and do drugs and he got me 2 stop that. I used 2 cut and o.d. a lot 2… he knows that and I swore 2 him that I’d stop, but my parents, family and school are terrible. last nite my dad told me that no one cared about me including him and my mom… I just cried and cried, then I felt like hurtin myself so I did the rubber band thing 2 keep me from doin it. it didnt help that much, so I decided 2 cut, it started out as just a few lil ones, but I started 2 feel a lil better so I kept doin it. I counted em 2day and there are over 20 of em. well, after I got done wit that I was still seriously hurtin… my dad’s words and the kids at school’s words (they call me things like a whore, bitch, fat, ugly, stupid, slut, hootchy, druggie, alcoholic, and a bunch of other things) just kept ringin in my head… I didnt want to kill myself, but just instead take the edge of the pain away… so I took like 7 advils, well.. I still felt it so I took more, a handful.. I have no idea how many… needless 2 say, I got reely sick, but I didnt tell my dad or anyone about it, well a few “friends” trying 2 c how I should tell my boyfriend.. I mean he loves me and he’ll try 2 help me but I dont want him 2 b concerned about me. I know I sound reely reely young in this and im not going to say my age, but I am not young… well, im an older teenager, if that helps. My family doesnt know about all of these things and what lil they do know they dont care about… 4 all they care I could die 2morrow and they wouldnt care, and yes, those are the exact words.. my boyfriend is the only one who truely cares about me and doesnt want me 2 get hurt… I know I have 2 tell him about this and I already feel guilt 4 not tellin him already… I need some help on this, on any of it… especially on how I should tell my boyfriend where he wont flip out and try 2 kill the people who have hurt me so bad… and by the way, I dont want to hear the usual shit bout how I am young and cant b in love (bc I am or I would have finished myself off last nite), or how I need some professional help, or about how I need 2 tell my parents bc they reely dont give a shit about me (exact words once again). so yea, pleeze dont go there with me…
