Hi Boydr,
Hot days always make my anxiety worse too, and I don't go anywhere without my water bottle and food. So you're not alone with that!
In Australia we have public health care, but I have no idea how it works in America. Have you been to your GP? They can do a referral and maybe talk to you about medication or other options if you want to. This program helps, so keep trying :)
All the best,
Kaitie.
