Recently diagnosed, endo claims that I caused my Hashimotos by taking birth control

Hello! At my yearly physical I mentioned some of my symptoms (fatigue, brittle hair, occasional dizziness, brittle nails, etc.) to my PCP. As a part of my routine bloodwork she had my TSH measured and it came back at 5.6. She then ran a thyroid panel and a few days later my TSH was 7.5 and my TPO antibodies were at 230.

My PCP recommended that I consult with an endocrinologist regarding treatment. My experience with the endocrinologist was very bizarre and quite frankly, uncomfortable. Without looking at my bloodwork, he immediately began drawing a diagram to explain the menstrual cycle to me (I am a 28 year old woman, I am very aware of the menstrual cycle.) He proceeded to say that although I do have Hashimotos, my problems will all be fixed if I stop taking birth control. He spoke in a very condescending way by saying things like “it’s a shame you don’t even understand your own cycle” and “I don’t know how you’d expect to have energy if you are someone who works out consistently and takes birth control.”

I was so surprised that he did not have any concern with my levels. The only treatment he recommended was stopping birth control immediately. My family does have a history with autoimmune diseases, but Hashimotos is new to me. Any support or advice after this appointment would be greatly appreciated!
