Social anxiety was HUGE for me. Amazingly, the more sober time I get, the easier that gets.
When I go into those situations, I tell myself I am NOT going to drink. There will be alcohol there and I am NOT going to drink. If I even suspect that my alcoholic mind is going to pop off with, 'just this one'......I cancel my plans. Seriously.
I guess I set myself up to succeed.
That first year is a set of learning experiences....at 9 months....it looks like you are doing well! Have a good time and lots of club soda!
