Hello everyone!

I would like to talk about this phobia that I have, or I think It's a phobia... I'm not sure.
Everytime I go into a shop o supermarket (alone) I always have this fear that the staff or security guards might think that I'm stealing. So I always behave weird, like if I don't want them to think that I'm stealing, and this behaviour makes me feel unconfortable. I really don't know what this is about!
I just want to do my shopping in peace!

Does this happened to any of you?
