Sorry to hear your story. Been there, done that. Awful experience - I've never felt worse in my life. I was also told to take 2mg Arimidex. It completely killed my estradiol. I had no idea what was going on. The doctor didn't know what he was doing. Like you, I finally just stopped cold turkey. It took a few months to normalize. I later learned that I could only handle 0.25mg of Arimidex per week max. Starting three years ago, I stopped Arimidex entirely and have never felt better on TRT. Good luck finding someone who knows what they're doing.
