I would start now putting yourself in social situations. It's like anything, the more you practice, the better you get. I'm 57...I've been on this SA path a long time. You have to break out of your comfort zone. I auditoned for a play a few years ago, a small speaking role. It helped a great deal to increase my confidence and fight my fear of speaking in front of people. This is the real me, the one from my childhood, who was not afraid, who was full of confidence. I am finding my true self again. You CAN be healed from this...but you have to fight your fears and that helps change the way you think about yourself.
