Because motivation increases and you can feel (most your emotions now) and you want to do something about it, so things that would make you mad/annoyed in normal life, piss you off again. I had way too many issues to care about things like facial hair coming back, or sex drive, until major things were resolved or on their way to being resolved. Same kind of thing, once I get to 80% if sex drive is only 60-80% I'll be more pissed off about it. But at my worst, it wasn't really on my mind except for testicular shrinkage (which freaked me the fuck out).
