Self-confidence should not be confused with self-esteem.
Self-confidence is inversely correlated to the power of your superego.
Your superego is trying to protect you against harmful social mistakes.
It strengthen itself when you are hurt (socially) and is usually modeled after the paternal authority and is often perceived as a kind of internal moral figure.
Gaining self confidence is the same thing as loosening the grip of the superego.
You can do that with alcohol, to some extent, but there are many undesirable side effects, including worsening your self confidence in the aftermath.
My advise would be to experiment doing "risky" things in a controlled environment where you won't be hurt.
There is no magic trick, unfortunately, success is what lead to self confidence.
(That is, teaching your superego that you can do social things without shooting yourself in the foot)
