I have a panic attack nearly every time I go into the movie theatre. Sometimes I wonder if it's due to buyer's remorse, considering what I just spent on tickets, popcorn, and drinks. Seriously, much of my anxiety stems from financial insecurities, and spending is a trigger. It's strange, but, if I have a bottle of water to sip on, it seems to keep me in the moment and help thwart the panic symptoms. I have to sit on the end seat. Otherwise, I can feel myself getting vertigo and feeling the need to get the heck out of there.
I also get this type of panic attack after eating in a restaurant, not during. It's right around the time to pay the check. It's like I can't sit there and wait, and again, I just have to get the heck out. Once I gave my debit card to the people I was with, told them to just pay and sign my name. I ran to the car and was able to calm down.
