2nd AC treatment done and I am Struggling emotionally

I think after a couple of treatments, the reality of it (whatever your reality is) steps in.  If you can, try to find some routine that works for you.  For me, the first few days were a write off, but after that I could start to do some things, usually in the morning when I had more energy - taking the kids to school, shopping, exercise, etc.  Afternoons tended to be be catching up on Netflix.
