I'm done with drugs and alcohol

[abstrktion]

Well done Great Spirit!!
IMO, drugs and alcohol will never "help" anyone hold a job, be responsible to and for others, or develop their own strength.
It probably won't be easy to leave them be though--if using drugs and alcohol was a coping mechanism, you may find yourself back at the stage emotionally where you started because you used the drug instead of developing the emotional control and stability that comes with facing and meeting the normal vicissitudes of life over time--I will always say that being young is more difficult than being older. The teenagers I teach don't KNOW yet that "this too shall pass," "I will love again," and "this won't matter in the future" because they are too young to have seen this proven out in their lives. Older people have--I KNOW I'll be ok no matter what; I KNOW that I can handle what comes--age brings confidence--not that you'll always have the right answer, but that you have the ability to figure something out (I'd call it the MacGyver factor from an 80s action-adventure show).
(on a side note--I had a recent realization that I needed to work more on my ability not to react to certain catalyst in a negative way...and then followed the realization that the only way to "work" on that was to be presented with a lot of that kind of catalyst! So I "unwished" that as fast as possible and asked to learn in my dreams instead!)

Best of luck to you Friend!!
