<human>: Can you give me the gist of the text in a nutshell?

I'm home from university and got invited to a bar by a girl and her friends that I used to go to high school with. Me and her have been talking recently, we reconnected even though we didnt talk much in highschool.

Problem is is that in high school i severely suffered with social anxiety. I didnt talk to people much and i had a really horrible 4 years. I went to university and i met alot of new people and now i have a couple really close friends, though none of them live around my hometown.

I thought I got over this problem but obviously I didnt. If anyone can help me understand why this is happening I would really appreciate it,  dont have anyone to talk to at the moment so Im sort of freaking out.
<bot>: Girl from highschool asked me to go to a bar with her friends for new years, my social anxiety from high school is returning just thinking about the scenario
