Oh wow, you sound like me in college. So here it goes...dry yourself out for a bit, not for ever fuck no, but a sober month. Then do what comes natural. Doctors can be awesome, but you might have already broken doctors for yourself. First step, eat something tasty and nutritious, second step, walk around and dry out. Third step ????
I was going to be something too, now I'm a 30yo produce boy in rural AR 1000s of miles away from any family, except my kick ass girlfriend, and her family, and the animals of course, we're thinking about starting a small flock of hens come spring time, if we can keep our dogs more or less sane about it. You know? I'm pretty happy actually making less than 10$ an hour in bum-fuck no-where. You might have a better future than me still.
