Am so so sorry you're experiencing such trauma, again.
If you have a pdoc tell him, also tell him you feel invalidated by psychologist.
Sounds like you need to find a different T. Someone who'll take you seriously.
Have you been prescribed any meds & do they help? You may need meds adjusted.

Please know I believe all you say. Don't give up!
With the right pdoc and T you can get some relief.
Won't be quick or easy, it's work, emotionally, but very worth it. There is hope!

Take care of yourself & keep posting.
