Hi Pixielouwho,
I am going through a similar but not quite as severe experience. I had a hip replacement 5 weeks ago and at the 3 weeks mark I got very depressed. Being at home, still not able to do much and not able to do the things that normally help my depression, such as exercise, was tough. I also felt useless since I could not do my usual chores. I work 3 days a week and went back last week. Although I was exhausted, it did help my mood.

I am sorry you are going through this. It sounds like you are having a really hard time and not getting a lot of support. I'm glad you have therapist to talk to about it. I will be thinking about you and hoping for a speedy recovery (and speedy approvals for treatment)
