I hear you, bluemountain. I get by on the seat on of my pants most days at work. I know how that goes. I hope your depression passes.
I saw a saying yesterday that I really liked. It says "I try to get by one day at a time, but sometimes several days gang up on me at once."
Even though he was your abuser, it is still a sudden emotional change in your life. Both good and bad stress can have the same effect. Confusing stress, too. I hope you feel better soon.
