PTSD from something silly

Apologies in advance for this, it’s very small compared to a lot of stuff that gets posted on here but I just need to get this off my chest.

Last year I went on a trip and I accidentally left my purse hanging in the bathroom stall. When I realized I left it I came back to find it gone. Someone had stolen my purse.

I rebought the same purse, wallet, and replaced everything inside that was replaceable.

It’s been a year now and every time I think about it I feel like I can’t breathe and I get this horrible feeling like I’m going to die.

I don’t tell anyone about it because it’s just a stupid purse and I mostly got everything back. People go through much worse.

But what bothers me is that person is out there and probably doesn’t even feel bad about it and got everything in my purse. I wonder what portion of my purse got thrown out, and what is still being used by them today.

How do I let this go? It causes me a feeling I can only compare it to anguish, and I only ever feel that feeling when I think about the abuse I went through as a kid, so I know it’s really affecting me.
