Does anyone else feel unlovable?

Hello. Just trying to make sense of it all. I'm a profoundly lonely person, even when I'm surrounded by others. I feel very unlovable, and like I'll never be loved in the way I wish I was. I don't know how to express this to other people. I feel I don't even understand my own emotions at the best of times. I just feel like I'm constantly disappointing others and letting them down, just by being me.

Does anyone else feel the same?
