I'm going to a rock concert soon: advice?

This won't be my first but it will be my first knowing I'm a HSP. In hindsight, concerts were always usually very uncomfortable for the first half, and then sometimes I would adjust and have a great 2nd half experience.

If it were up to me I probably just wouldn't go. But by now I've unthinkingly committed and bought tickets.

My plan is to just be okay with how much distress I am in and trust that after awhile I'll relax.

Sometimes the hardest part of being HSP is that I don't enjoy things the same way others do. I often feel disconnected and left out. I need HSP friends fast.
