Maybe lower your standards? ahem... I mean expand your horizons. lol
What keeps you from meeting people?
It sounds like you should work on your depression before you find someone. I have been depressed before and it seems as if that is the time I wanted someone more then anything else, but when I got out of it, I was fine by my happy self.
I believe it's really dangerous to start a relationship when you're already depressed and you can start by changing your fatalist attitude. Haven't you ever heard of "there's more fish in the sea" of "if you miss one bus, there will always be another one?".
Once you're happy again, you'll be a more interesting and confident person without actually changing! When that happens, you'll either attract more girls or you should be by then strong enough to handle rejection if you go out and take a chance of asking more girls out.
Maybe you're just going through a depressive phase to really teach you the feeling of loneliness and make you really want to be with someone on a deep level... who knows?
I'm sorry I can't help you out of your depression though, it's a very personal thing, but for me it was to learn to say to hell with jerks because even if they think badly about you or say bad things to you, in the end, they're just trying to help themselves and it's your own responsibility to avoid those people and situations though sometimes it's inevitable but in those times, just realize that it's something everyone goes through and move on.
Good luck.
