What are some good ways to enjoy life?

on most days all i want to do is drugs. i've abstained for over 2 years, but its never over. i feel akward in the sober state... pretty much just very supressed emotion while sober and when i drink, pop, snort, inject, etc. its like my being can finally breathe. i am a fish out of water while sober. things are just so pitifully mundane. its not like i just sit at home and watch t.v. either. I work, take engineering classes at the college, in a club, run, longboard, read, make music, spraypaint, mess around with electronics. maybe i need a girlfriend. someone else to focus my attention on besides myself. much easier said than done to get a girlfriend. i'm 23 and i've felt this way atleast since i was 16 so its well past a phase. i seriously just feel so damn empty inside.
