Drugs & Depression !?

Princesa
Hello, my name is Maikemae (My-Key-May). Yeah i know a boring way to start my post but i just wanted to smack to you guys . For starters i am very overweight , (260) 5'6 . BIG and my skin is too dark. I'm 17 .I've never had a boyfriend or been sought out by anyone except for a quickie. 
I've always had LOW self esteem and i've tried to kill myself over 5 times. My relationship with my mother is horrible (don't even wanna speak on my father) and i often times find myself depressed , and sad . Eating or sleeping. 
I've officially given up on myself and am just waiting for the day that i perish. Lately i've began taking up drugs, though. 
I have started buying and smoking marijuana, trying acid (LSD) , popping pills including Xans, Opiods, and a few i don't even know what i've taken. I've done esctasy and I've also been trying to get shrooms and other drugs but i'm worried these will soon lead me into more hard core things .
The drugs had become the only way for me to escape my sad depressing life . 
Lately i've been running low on funds and can't seem to find work anywhere so i haven't been able to buy the drugs like i want and need and i've been falling right back into my depression. i've been trying to kill my self more lately and haven't been happy since the last time i did drugs.
i've been to a mental hospital once for suicide and found it pointless if i'm still in this depressing state and TBH i know i need the help but i find it another waste of time because all in all i just don't want to be on earth. Plus i can't seem to bring myself to tell anyone what i'm feeling or where i am . i just don't know what to do with myself anymore.
