Sometimes taking a break from pdocs and all that is worthwhile. I did that for a few years and recently went back to therapy and it is much better. I don't see a pdoc since I refuse meds these days.

If you are losing so much weight so quickly, please see a real doctor about it.

I had a pdoc order thyroid tests because of some nasty side effects from Ziprasidone. It was a hoot. He kept writing the lab order wrong and after the third time I got poked my primary doc(in the VA system, she has access to what every other clinic is doing for me) took over and got it right the first time. She has no patience for pdocs but VA policy forbids her from prescribing most psych meds. She told me he kept ordering diagnostically invalid tests. It felt to me like this was something an intern would know.

Ordering tests like thyroid and other such things and brain scans to rule out physical problems should be something they do early with each new patient, but they don't.

If your primary doctor agrees to write your prescriptions, it might be the best thing for you. Any lab work will also not go to waste since he/she will be able to make sense of the results and provide any needed help.

In my experience, every pdoc has a list of pet meds that they work through until you hit on something with a good benefits/side-effects ratio. There is no science in it at all. It is like playing darts or whack-a-mole.
