Pain in the You-Know-Where

I wonder why jobsearch ALWAYS gives me a headache.
Why do I ALWAYS end up completely freaked out after a couple of hours spent with jobhunt? My mind goes completely blank, and all I see is this vaaaast blackness instead of a more-or-less successful future.
How on earth will I EVER find a proper job with the education I got?
Seriously, it's a complete and utter MISSION IMPOSSIBLE.
And, I assume, it will not get easier once I have a degree under my belt.
Not even a tiny bit easier.
Will it?
