Hi there, what you are feeling is soooooo normal. I had to go away for radiation after chemo and when I got home everyone was in need of a big celebration and I was feeling like I was barely functioning. I would advise you to take things slowly and just ease your way back in. I ended up having some really great phone counseling from a cancer council psychologist which I found helped. I also walked every day, just being out there helped clear my head, it's something I have kept up and am now the proud owner of a Fitbit courtesy of my hubby.
Hugs
