Melancholy, stress, feeling insecure to be loved?

How can I deal with these three? They’re all connected to the last ‘problem’. I feel like I don’t deserve love. I mean, I do like my personality a lot but physically I feel like I need to be perfect, have a perfect relationship, life, career… And I can’t go ahead and have that, take chances, because I feel insecure that I won’t be loved anyways. I am a weirdo, why would they love me?
