Therapists often try to diagnose, but they're not necessarily qualified to diagnose.

My therapist happens to have a PhD and he does neuropsych evals for diagnoses, so I consider him "qualified" to make a diagnosis. But my old therapist? She was a crazy middle-aged lady who only had a Master's and never did neuropsych evals. I ignored what she had to say. lol

Could you maybe talk this over with your pdoc? Your therapist has her opinion, but your pdoc has theirs. Your pdoc knows how you've reacted to different medications, and has some experience with you. Pdocs are qualified to make diagnoses
