I left a good job a number of years ago due to anxiety and I also felt very ashamed, embarrassed, etc over it. I was just out of grad school and had landed a good job but I was not prepared for the level of work this position required and I was so stressed. I didn't give a resignation - just quit - and it was not the type of thing I felt good about to say the least.

I took a few months off, got some counseling, and then went back to work. It was not easy going back (I had a ton of anxiety and my confidence was rock bottom) but I took a less stressful job initially and worked my way back up over a couple of years to where I had been.

I don't know that I have much advice ... just my own experience. I hope the Lexapro will help and staying with a psychologist is important. You've had a lot of losses to deal with in recent years. Those of us who have had struggles are not bad people ... just humans trying to find our way under challenging circumstances.
