Does someone relate to these symptoms?

I've always suffered, although not often, of panic attacks. Nowadays though, I'm noticing the circumstances are pretty weird.

I mostly have them somewhere I'm not fully dressed (be it a bathroom or the pool, or in a less covering dress), and they come from no external stimuli, but seem to approach all of a sudden, and the only tell I have is that I'm very thirsty.

These things have happened since I was small, and I'm talking 6 years old small, as small as I can remember, often enough so that I eventually brought it up and got called overdramatic.

School made these panic attacks more frequent, and outside of such schemes. But now that I've worked through those, it seems like the original ones are still there.

I can't seem to figure out why they're happening, can't remember anything that has to do with similar situations.

Does anyone have a similar experience?
