My feelings get hurt easily?

I am SUPER sensitive. I can't help it, I've always been that way. If you reject me, say something negative about my performance/looks, or even DON'T acknowledge my presence ...... tears WILL spring to my eyes. Even if people are just being ''real'', or harshly honest, I just can't take it. I want the truth, I hate when ppl won't tell me things in fear of hurting my feelings, but when I get the truth, it mostly hurts. How can I grow up in the real world like this? I'm already in college. It gets worse since people there are more honest/straightforward.
