I don't have personal experience with it, but had mentioned it to my T when a good friend was considering it. He said from what he's heard from clients, TMS did not tend to help much. ECT and the clinical version of ketamine (there's a nasal spray and I think an IV version) were much more effective. But that's anecdotal evidence, and everyone is different. If insurance will cover it, and you can also spend the amount of time it will take, it seems worth a shot.

Oh, and I almost forgot--ex-T had suggested it to me at one point, like 6 years ago. However, when I mentioned it to ex-p-doc, she said that because I had both depression and anxiety, she wouldn't recommend it, because it hadn't really been studied for anxiety--her concern was that it could potentially have caused my anxiety to increase. But studies may have been done since then. You mentioned trauma (I'm assuming PTSD/cPTSD?), so might be good to check into what research has been done in that area regarding TMS and its effectiveness, plus potential side effects. Perhaps that's something your new T might be able to show you? If he has some research on it?
