Looking for any thing/ any ounce of hope

I have been trying to find work for since january. I 'm work in computer for a trade. I am A+ certified, dell certified and have a A.S. in Info Sys. I have been told I am overqualified so many times I can't even count. But still, interview after interview I don't get the job. Some jobs I been of two interviews just not to get the job at the end. I have done all I can do to see what I'm doing wrong. I research and practice my inteviews. When I think I got the job. I don't hear anything. When I call to find out if the job positon been fill, I get " we will let you know when you  are hired".  I so qualified I can't even get a call center job. I am so F**cking overqualified I may just finding a fastfood job to pay bills. I know jobs are tight but DAMN! i SHOULD GET SOMETHING! I live in So. California where my rent is $1200 just for a very average apartment. It's tough when you are a married man who just want to provide for his family. The feeling is like a female don't have a child. It is tearing my apartment. I have prayed and prayed but I don't hear  anything. I cried out to God just for any help. I just want to do the right thing but every door is shut. I just want to hear one word of hope.
