I can't get over how hard it is trying to understand if I'm reacting to something whether that be good or bad in the right way. 
A lady yelled at me the other day. Bear in mind this is all down to the corona virus. Not just some weird shop.
Anyways, I was a customer and she was staff and she shouted at me because I didn't adhere to some signage that was left out advising customers to stay a metre away from the counter. I did this until my turn to be served.
Some guy finished paying at the counter so my turn...
I strolled over to the counter and she shouted at me to walk around ....there was nothing I might add to walk around. There was duct tape on the floor. This is a hardware store mind so you come across this regularly right? Just tape on the floor over cracks and stuff. It wasn't straight or laid out with care so I had no idea she was shouting at me to stay behind this line of irregular duct tape. 
She then legit bellowed at me to get behind the line. Considering it was irregular I was already behind said line. To which I told her I was getting angrier and angrier by the second and starting to tear up because I hate situations where I feel I cant control myself in public. 
Anyways she didn't apologise asked me what i wanted then proceeded to tell me to stand at the counter to pay. Bear in mind again pleade that if I'd have been stood at the counter, we still would not have made contact because she was in the back room getting all my items. That's how this shop works. Order, they go get it and give it to you and you pay. 
A colleague of hers laughed along with her whilst she was shouting at me. And look, I'm not an easily upset person. But this lady shouted. Full on. 

I got into my car and cried all the way home. I was shaking and angry and upset. But I cant get it out of my head. 
Was I over reacting? What if I'd have shouted back at her? I genuinely hate it when I don't know if my reaction was plausible. To me it's the worst part about this illness. Am I acting okay for the situation I am in is a constant question in my head and I'm tired.
