Sorry for your bad weekend. Apparently, we had the same mojo (or lack of it) going.
OK, you are angry and hurt, and you have a right to be. BUT (there's always a but), this is not the time ot make any big decisions. 48 hour rule: Wait 48 hours before making a decision. If it's a good idea, it will still be one in a couple of days. Take this time to cool off.
So, can you identify what really has you upset? I mean the absolute root cause of it?
We all get frustrated, sad, and angry at times. I'm certainly proof of that. How we handle it is up to us.
