I've really been needing some help. too many emotional/addiction like problems to handle.?

I'm 16. Through out my life I have moved. within 5 years i lived in 3 different states in different parts of the country. also, i have a small memory of when i was young of possibly being molested but im not even entirely sure. before i moved to the state where i live now when i first moved to where i was in in 6th grade i always thought i was fat and i would never eat, and the same in 7th grade. my mom would never notice (she is a psychologist) and would always not notice also bc i would still try different foods. when i moved at the end of 7th grade thats when i began cutting myself. she was concerned, but didnt get me into therapy until a while later. i went for a year and just stopped. it didnt help at all. i kept cutting and that became a ton of substance abuse and cutting on top of that and also i had an eating disorder my mom failed to admit to, just saying i had a fast metabolism although my doctor forced me to go to a nutritionist for at least a year and a half. recently, i told my mom i was having substance abuse problems and that i was using that stuff to cope with my depression because i had a really bad reaction to laced weed and my heart rate was up to 180 so i had to tell her what was going on. i asked her if she could find me a therapist because ive really been having problems, and she said maybe and she still wont get me help. and has been acting as if nothing happend. within the time i was really having a hard time with drugs, i was constantly coming home high my grades were down the drain and i actually was 95 pounds and looked like a train wreck. I have been feeling like no matter what i do, I will never get the help i have been needing for so long and i was wondering if anyone could please give me any hotlines advice with what to say to my mom or anything. please???
