This probably sounds super odd and paranoid but I absolutely hate going on walks by myself. I usually walk my dog with me, but that tends to make it worse because she pulls on the leash a lot and acts horrible which is embarrassing. Anyways, my thought process goes like this: 

What if the cars passing by are looking at me and judging me? What if someone I know is driving by? Why are my arms swinging like that, I look like a monkey. Should I put them in my pockets? What if people in their houses are watching me? This is so embarrassing. I need to go home. Now I can't breathe. Why can't I breathe right? What if people see me right now and think I'm weird? 

And thus a panic attack starts. I don't really know what to do about this either because I actually just live in a small town as well which makes this seem ridiculous and irrational. I try to go on walks daily because people say that its good for your mental health, but even anxiety is ruining that.
