My Fear of Rejection

I fear rejection, like every day. Its stressful, and I hate it. I just want someone to truly accept me. I always have to cast my eyes down in shame whenever someone looks at me funny. Am I really that ugly? Do I have to go back to wearing a hoodie all the time, just to hide my face? I like to think of my hoodie as a safe place. Its my comfort place whenever I'm upset or lonely. I don't wear it anymore, but I'm still self aware. I actually used to be emo but no one would have really guessed because of the way I am now. I'm a bit more perky now and a lot more friendly and caring. But now its getting old and I'm starting to act like a child too much and its annoying. I'm thinking of changing my personality again...I don't know. I feel like a total fake. Are they going to reject me if I do change again? Idk. How do I admit my feelings to a guy I like without fear of rejection? My fear of rejection is always going to get in the way &I'm going to miss a lot of experiences if I stay this way.
