No one has ever liked me back EDIT

I feel down in the dumps. I confessed my feelings to a friend and the feeling was not mutual. This was two months ago. I’m still hurting from it.

No other guy that I have liked/loved have had the same feeling for me. I dated one guy shortly who wasn’t affectionate at all and it turned out he was just “trying me out” and decided he didn’t like me and broke it off. What do I do? I feel unlikeable, like why can’t somebody give me a chance and have it work out for once?

Edit: Just thought this was worth mentioning: I am 25, so I’m not a teenager anymore. Also, I do like myself, quite a bit actually, and I can stand on my own two feet. But when you’ve been rejected time and time again for years it really starts to chip at you!
