Pendulum,
Man, your post sounds eerily familiar. We're EXACTLY the same (minus the degree). I got sober for the first time a year ago for 28 days. Twice since for 2 days. And now I'm on day 6. One thing I've learned during this journey is that drinking, for me, is an attempt to cure or salve the pain I feel.
Like you I'm extremely disappointed in life. I hesitate to give advice, since I'm barely off the drink, but I can tell you that I'm glad I'm sober and that I don't want to ever go back to that life.
Yes, I'm still disappointed in life. I'm almost bitter at the way my life has turned out. I'll get bored. I'll pace the floor. I'll read. I'll go to work. I'll keep looking for a new job...a nice girl...but I WILL NOT drink again. I hope you don't, either. Maybe this is just the beginning of our journey.
