Just 2 quick notes:
One is, tell them about this, about your cycle and what happens; it's important and part of the process. They can halp you with it. When you break the cycle, as you already suspect, you'll start feeling better, I think.
Two.. commit (like I am this time) to going to therapy even when, and especially when, I feel like stopping. In fact, when I feel like stopping, that is my cue that it is time to stay put. It's hard, but I think it's really important.
Sice you cycle, if you stay put and hang on, I'll bet you'll get back to where you like the docs and take your meds again!
