Welcome Trudy
I think the most depressed I got was when I found out about my second cancer. Up to that point, I thought I had the cure ...oh well. I have been on lexapro off and on through the years. I have not used it in a year or so. After a while you just find a way to find the joy. It is part of being a human being. I just found out about my 4th cancer, and was depressed for a couple of hours I guess, but I am kind of shrugging it off now because I know I will soon get rid of my pneumonia and feel a lot better.
Good luck with your treatment.
