Going to a hockey game with my dad tn but I’m anxious about it there’s gonna be a lot of activity

I’ve been hyper focusing on my breathing lately and I’ve been having dizziness going on for a few days and all I can do is keep over analyzing it.

Today I felt really overwhelmed and lately I’ve found my self overwhelming myself and doing to much everyday. Because I sometimes can’t say no. Any thoughts or recommendations

Anyone else have horrible anxiety at the holidays having bad right now any tips?
