Deserving love is different from deserving a girlfriend.

Love is something you can spread around to multiple people. It can be anything from fraternal love for a co-worker you've gone through some rough experiences with, to romantic love that bonds you to one specific person.

Everyone deserves love by default, although some people hurt other people and stop deserving love. But, deserving love and deserving the 1:1 commitment of a girlfriend are very different things.

If you're a kind-hearted, hard-working, trustworthy person who was raised with some fucked up beliefs, I'd say you deserve to be loved. Hopefully one of the people who loves you can take you aside and explain to you why your fucked up beliefs mean you can't get a girlfriend. Hopefully that loved one can help you change so that a girl might want to make a commitment to you. But, nobody really "deserves" a girlfriend. They aren't awards that can be handed out once someone completes the required steps.
