What's the recommended dose for anastrozole and how often?

I'm just 19y old and I'm tired of being focused on my health because I have other things to do at my age, but in the last 2 years I started to develop the symptomps of chronic fatigue and fibromyalgia. I have trigger points in my whole body and my muscles hurt when I touch them, I'm extremely sensitive to cold and I have tinnitus. I'm constantly fatigued no matter what I do. I have muscle spasm especially after walking, and it doesn't change no matter how many electrolytes I take and so on I optimized my lifestyle, diet, and all these things, I've tried everything I could. I took all the supplements and all these things and I invested a lot in this problem but with no results. I've tried keto, I've tried everything. I don't know what to do at this point. I'm willing to take any drug that can fix this because I don't want to live like this anymore. All I want is to train and get better in the gym but I can't. Everyone explains this as " central sensitization" and all of them want to sound so smart but none of them give a fucking solution. My mental health is good, my lifestyle is good, I've optimized everything, what it is wrong with me??? I started to take TRT because I thought that it might help, but I still have these problems. I can barely train or do anything because of this I don't know if you know him, but Dr Trevor Bachmeyer made a video on chronic pain and one week ago I started to take BPC 157, TB 500, KPV, Semax and Mots-C, I hope that it can fix this. I would appreciate any advice. Thanks
