I personally tried to bulk up, and no matter how much I lifted, I was never happy. Now I am just letting my muscles go away, since they never made me happy. I can't stand looking at my lifting progress pics!

From my experience there is no way to cure the dysphoria without transitioning.  I can lessen it with my attitude.  That although not the ideal body, it is the best one I can have given the constraints I have.  That lessens somewhat for me because I have tried the best I can to do something with what I have.
