I suffer from this,
probably the worst case you can get,
let me describe to you how this wall of fear is within myself.
Its so bad, that I dont even make EYE contact with attractive girls, and I only look at them when they are looking away - much less talk with them.
I am 22, have a growing successful business, great self educated, lots of business contacts, connections, etc. Independant, TONS of confidence ...
