Thanks everyone.
Yeah I talk to her about it - I know some things do affect me permanently, like there are times when her brain injuries are really obvious in memory or mood swings, etc... and it's like an instant trigger, I have to like immediately go get high (i'm an opiates person). But I don't quite tell her that much but I always try to let her know that I love her and am there for her, but when she doesn't change her actions or take advice, I just don't know what to do.
Another thing that I can't really talk to her or anyone about is that there was a girl who did chemo with her, and I was about 14 at the time an she was too (my sister was 11) and that (for me) is like the beginning of dating and stuff and I kinda dated this girl a little and I really liked her - she was on round two with lukemia and it went into remission - she had lost a leg from it the first time, so she was an amputee, but was just absolutely gorgeous, i can never ever forget her face - she went into remission and we kept seeing each other throughout my sisters treatment. Well she had a relapse,s o it was her third battle with lukemia, and I know she was on heavy pain pills, fentanyl and hydromorphone I think, and she tried to fight it for a couple months, but she was in so much pain that she died. I think she took her own life, cause of death was a massive overdose of hydromorphone and fentanyl, she was smart so I don't think it was an accident, but it was never said whether it was intentional of accidental.
That fucked me up, I think, and I think it has something to do with my drug of choice and sometimes destructive behavior. And I've only ever talked to one other person about this - I don't want to put my addiction problems on anyone because they are mine alone and these people went through so much more than me.... fuck. i don't know.
