To be honest, to change is something that takes long enough to be irreversible, you've been raised one way, and will keep that way, if not, most of your past will keep inside you, reminding you of how you were, I know your attitude really can be worse as you explain when coming to socializing, but you know, only you can change that and the way you are by own will of thought, if you consider yourself that bad, you by your own should abide by it, simple enough as "I can be bad, then I can be good", it's really up to copying the good example of others.

And your girl... she came up with you because she loves you for the way you are, think a bit, you may ask her how does she feel about you when you think you have done things wrong, then you can point out and correct the flails.

Go on with life, it's a lot to learn.
