There have been several periods throughout my life when I started low dose HRT to "Stop the noise" as you put it. I called it a brain reset. At those times I had given up on any thought of transition and was resigned to trying to be a normal(ish) guy. Stopping HRT was always preceeded by things not working so well below the belt. Which is a direct contradiction to being a guy. But the "Reset" was completed weeks earlier. Of course, like other wishes it wasn't a permanent fix and the cycle repeated several years later.
When I decided 6 years ago to take on the trans-beast for real, I also had a few WTF am I doing periods. Got depressed, stopped HRT and the death spiral of even more depression and anxiety came. The longest was about 2 months before I had to admit I was only kidding myself. I really do need it if I never want to be that lifeless soulless thing I was again and wanted to continue to enjoy feeling alive
