Still no luck

How does one stop feeling sorry for themselves and not go into depression when they loose something important to them?

I'm having a hard time with the losing my job thing. I've submitted a slew of resumes but no responses yet. A lot of the postings don't close until this upcoming week, but some have already closed and I never even was offered interviews. At least I recieved notice the jobs were filled.

As time goes on though I find myself feeling sorry for myself more and more. I can't help but question everything that's gone on until now. Such as, was it really corporate who decided to get rid of me? Or was the regional manager merely told to get rid of X many people, and he chose me?

He never liked me, and I sure as Hell didn't like him. Or his buddies.

Anyway... I keep trying to force myself to get up and out and do things, but I'm starting to lose the motivation.
