I decided to take a mental health day today, as I've been really busy recently and don't have to be anywhere. I thought about going swimming; it's hot but also smoky from fires in a neighboring state. My friend called me saying she, her boyfriend and a mutual friend are going to the park by my house to swim and offered to pick me up. I immediately got anxious and said no, thanks for the offer. We hung up and I regretted it and started agonizing about calling her back and accepting. It got so bad that I started to panic and had to take an anxiety pill. I have pretty bad PTSD from an accident and am medicated but have yet to experience this kind of anxiety. Now I'm just hot and annoyed with myself that I'm not in water.
