I say screw all computer related things for a week or two. Go out, and find yourself a girl. It's not that difficult...just behave confidently, smile, and...it's been said before, and is exceptionally cliche...but hell....be yourself.
Don't act differently. It'll come back to bite you in the ass one day.
Get out there and just...socialize. Either you go and do, or you just don't. If you choose the latter, your right to bitch is automatically revoked.
You're not a bad lookin guy, Duff. Take steps to bolster your basic self-esteem, and you'll be fine.
