How to overcome rejection?

Time and others.

That's the bottom line.
It sucks but that's how it works.

One day you'll feel like shit over someone, then the next you'll meet someone and forget why you were ever so upset about the first

Don't let the feeling fester. Move on fast and keep looking.

I wish I could help you, but I can barely help myself.
Though you just might think it's not the end of the world and this rejection must be seen as experience, so you can deal better (and also succeed) in the future.

I don't know.
I got rejected by a long-time crush last week and its been fucking tearing me up. She's really special. One of the only girls I've ever connected with on an emotional and intellectual level, and also found sexually attractive.The thought she finds me inadequate to be a partner, and the thought that some other guy will have her is killing me. I really don't know if I'll find another person like her.
