Frustrated and Demoralised

I have been feeling frustrated of late. I am frustrated at myself for not getting a proper and stable job. Most of the jobs that I've done are on contracts which I now detest. Why can't I get a proper job? Is it because I dont have enough work experience / I'm not suited for the job / my degree isn't recognised or what??

Secondly, I've been trying to ask some girls out but so far the response has been lukewarm. Is something wrong with me? But then again, I can't really blame them because I dont see them most of the time..I'm tired of asking girls out..Everytime I try, I hit a very hard brick wall...it is THAT demoralising.
