Oh, rio, I'm sorry.
It does sound like that brought on a panic for you. I've been there. It's miserable and very scary.
When my anxiety is really high, I can feel like I will be in "horrible" (unrealistically) trouble for something.
Again, I'm so sorry this happened and, except for the after effect, you're feeling some better. It's hard to remind self that it's going to be OK when feeling so much.
