A coworker at work today was completely out of line today. Giving me the worst attitude, ignoring me, short one word answers, but being so cheery with other coworkers. I left work at 4 and I am STILL agonizing and dwelling over this. 
I feel like a terrible person and I literally didn’t do anything wrong!! I can’t sleep my anxiety is so high. 
And I keep circling around thinking, “what did I do wrong??” 
This anxiety is just sitting with me so terribly. 
Has this happened to anyone else??
