hey yeagerx, i think you already see booze and a few other substances aren't improving your life. and i'll bet you feel even more depressed the day(s) after a binge.
i really want to focus on your "edit" and encourage you as much as possible to pursue your music, writing, art, whatever creative pursuit that makes you feel better. music, writing, etc can be a fantastic way to express your feelings and release all the anger, confusion, fear, just everything that complicates life. in all honesty, writing helped me more than therapy or psyche meds or recreational substances. i was able to work through a lot of negative crap and just let it go. life throws some wicked curveballs, so to speak, and dealing with stress through your art is way more effective and positive than getting so loaded that you pass out on some stranger's lawn.
i cannot encourage you enough to pursue your artistic interests. i'm older than dirt (46) and been on my own since 15. i made a lot of mistakes but i did stay in school and got my degree. and a couple years ago i decided i'd let some people read some of my writing, submitted it to an anthology, and they printed it! shocked me. the same thing could happen for you with music
listen to what your body, brain, and heart are telling you and get high from your music. there's no drug that can duplicate that feeling.
best of luck to you.
