android: At your age i were pretty much in same situation. My relation to my parents were really infected because of my way of life. The only solution i could work out with my dad was to move away. I moved to the other side of the city and left all my friends that i hanged with, they had already gone to worse things like car and house burglars, sometimes while doing drugs. Although we had knew each other from childhood stealing from me also became a way for them to get their own fix.
I met couple of them after I had moved (they had stolen a car and came to do some weed in my new flat), but at that time i had realized that i had nothing i wanted from them anymore and wanted to go on with my own life, which was being really unsociable, like 4 years or so.
It has taken ages to start sorting my life out, figuring out who i am and my needs. But i know i over think things also
The gravy to use something to fuck up my mind took the longest time to get rid of. I even today can think it would be exiting to a proper extent but have a decent life with children and wife and I can fill that feeling with other thrilling stuff (and alcohol ) so its not a big deal for me anymore.
I don't know the situation for all my old "friends" but some of the guys it has gone pretty much down hill with stronger drugs, more and worse crimes.
I didn't perhaps use amph to same extent as you do, but it happened that I used it before going to my work as a cleaner for my dad. I hated that job so badly it helped me to deal with it.
My advice is to avoid taking such huge risks with your future because life is much more than a rush and you can learn to enjoy it without.
