How do I stop being so self concious? I feel like I'm not worthy....?

Unfortunately I share the same lack of self confidence. But you should not worry. It is a long hard psychological battle, sometimes you just have to take a chance with things. Every time you feel unworthy just remember you are your own worst enemy. Keep telling yourself you are worthy. You are worthy!!!!!! :) being single isn't something to be afraid. I know its really hard to find someone when you have issues with thinking you suck at life and aren't liked by other people etc. but focus on picking yourself up. throw your self out there to talk to people it has worked for me, although I myself still feel super awkward . good luck :) don't let you put yourself down, your a beautiful person.
