First - that body fat % on your scale is NOT accurate. The only way to get an accurate reading on that is a DEXA scan. My scale claims I am at 39.42% body fat. My DEXA scan (done at my doctor's office) says I am at 29.01%. HUGE difference. So, don't let that number beat you up.
As a long time sufferer of depression, anxiety, and bipolar disorder, I know where you are coming from. I've been off and on my meds for five years and where as sometimes it is...sticky...I pull through. But then I noticed things like, the more wieght I lost, the more...crazy...I became. Come to find out, weight loss releases hormones stored in our fat...OH GOODIE! So, fixing to get back on some meds, at least for the short term, again. But, now that I have been on jsut about every last medication out there, I know which one helps me...and which ones do not. Sometimes, you are simply on the wrong medication. What works for most, doesn't work for all. You should never feel like a zombie on medication; if you do, you need a new one.
However, all that being said, find something you enjoy. It will make the journey easier and not so overbearing. I discovered earlier this year I enjoy running. NEVER in a million years wouldn't have thought I would like that. Now, I run as much as I can. It helps give me my moment. Relaxes me. Frees me. De-stresses me. The days I don't run? Oh dear lord I am an emotional mess who snaps at anything within nanoseconds. Prior to learning I liked running, EVERYTHING about weight loss sucked. I hated dieting. I hated exercise. I hated not being able to eat junk. I hated cooking two dinners, one for me, one for my family. Once I discovered a passion, everything else kinda just seemed to fit nicely with it.
And fire your therapist. If they won't listen, get a new one. I think I had fired more than 50 before I found Chris.
I know your pain oh so well....
