["I'm going to a Braves game tomorrow for the first time and I'm a little apprehensive.", 'It should be fun! Do you like baseball?', "I love baseball, I just have social anxiety and I'm a little concerned with how I will react being in such a large crowd."]
I think you will be fine. If you need some alcohol to take the edge off, go for it.
I am very anxious socially and don't like to go out with large crowds. Tomorrow I am going to a MLB game with my best friend and her parents. I am apprehensive because this will be my first in a large crowd in over 8 years.
