You could go back to weekly and see if it helps. I have gone from a weekly schedule to every other week several times in my therapy. It just depends on my level of need. I do find it easier to keep up the "train" of therapy if it is weekly. When I go to every other week, it takes a longer to get back into it during session and overcome some shyness that has developed. Why don't you talk to your T about it and see what she thinks. I think, though, that you know best whether going back to weekly is what you need right now.
I'm sorry to hear things are rough right now. Sleep is so important. Hang in there.
