It's not necessarily treatment failure- I go through times when I feel upset and oreoccupied because therapy has basically taken a layer of skin off something that's a bit tender, but therapy is supposed to do that. And you've a lot going on just now and have just got through the holiday season. We all post from a place of personal experience and bias with some folk having less positive experiences than others.

It would be useful to talk to your T about your deeming worse as things go on and they will be able to help you unpick that. If you think there's something your T does that drives you feeling worse, it's worth feeding that back. In the meantime maybe do some relaxation exercises or journaling to help soothe yourself.
