Don't fret. I've done the same time more than I can count. Sometime it take a second pair of eyes, but usually what works for me is to leave it alone for a while and then come back later with your own fresh eyes. 

I had a Java assignment one time that I was puzzling and puzzling over for hours. I finally gave up and posted a question either here or elsewhere. I got a response notification so I pulled up the code before going to the answer and I spotted the error almost immediately.
