Hey Stuff69, I was in your position a couple years ago. You're taking the right steps by reconizing that it's there. I would suggest reading pickupguide and fast seduction. Say hi to every girl you walk by for a while. Just hi. This trick works wonders.
Just dont give up man,

p.s. keep learning and improving 24/7. Work on your body and mind, and girls will notice the change. Even if they don't right away _you'll_ feel better and more able to survive socially.
