I know exactly how you feel. I am the same way. Just reading the words in your post about the way your day was already made me kind anxious and it wasn't even me who had to go through that.

I am not sure it will help you, but when i get super anxious and stressed, I drink a lot of lemon balm tea and tinctures. Lemon balm calms me. And also CBD oil as @squishysquid mentioned has worked for me as well.

I really do hope you feel better. Sorry I don't have a lot of suggestions, but just want to comment to let you know that it's not easy what you are going through and I know just how you feel.
