Don't take this the wrong way: I'd be loathe to suggest possibly destructive behavior to someone who is looking for advice on treating a mental health condition.

I know what you're talking about.

And no, not since I moved back with my parents

(I hardly know anyone in the city anymore and I haven't been feeling like going to meet people ever since I did, since I always thought of this as temporary and I would be leaving anytime)

Now is the time to recognize your motivations and turn them toward something better. Hunting for a job is much like hunting to attract members of the opposite sex:

1) Everybody wants someone who is already taken 2) You can't win unless you play the game 3) To get a 10, you at least need two 5's

Stop thinking of the perfect job and start thinking of ways you can build your experience to get the perfect job. With a little bit of excercise (P90 and Cracking the Coding Interview), some hero moves shown in the right places (pick the job doing something you care about) and a few peeps talking about your moves on the scene (a little open source), you'll be back in the game in no time.
