I am going through basically identical symptoms you were experiencing. I have had crashed low E2 for a very long time and now it is actually causing my body to attack my healthy thyroid. I am looking at Graves Disease and have to take medication for it. I had all your symptoms, dizziness, accompanied by frequent urination causes by heightened anxiety/panic. Basically feeling like you are dying, the fear. Weird BP issues which I never had before, hair loss, skin sensitivity, dry eyes, teeth issues. And this was all caused by crashed E2 using an AI.
Only difference, is I am not taking any testosterone supplementation.
