Why was it so impossible for yiu to understand that your suoervisor DID NOT reject you. She was just forced BY YOU to respond to YOUR BAD BEHAVIOR. That is NOT rejection, that is consequences you received for your bad behavior. YOU gave her NO OTHER choice than to respond the way she did.

No matter what everyone told you, you just seem unwilling to understand anything other tgan the made up story YOU put into your own mind about what happened.

You need serious therapy to help you with this aspect of your life.
