My meltdown happened at age 43. I had a life-or-death heath scare that made me re-examine my priorites, went from 285 pounds to 195, then put on 25 pounds of muscle. Apparently this was a recipe for disaster. It seems the weight loss and muscle gain made my testosterone levels go haywire while my endogenous estrogen went way down. I became MISERABLE, and I could no longer ignore my gender issues.
My guess is that your muscle mass is keeping your testosterone levels up, which is fueling dysphoric thoughts. As soon as I went on estrogen, I felt a lot better. The more I took, the better i felt. When I got the orchiectomy, I had never felt better. If my dysphoria was a "10" (or "11", as we metalheads like to say) before, it's a "2" now.
My advice- get a qualified gender therapist NOW. If bobybuilding makes the dysphoria worse, you should probably stop. Life's too short to spend it miserable.
Hugs,
Jill
