Not specific to that particular problem but in general the best way to deal with dysphoria is to go with distractions, focus on work when your there, keep a good tv show around to keep your mind occupied when your not, and try hard not to think about it. I wish I could be more help but hell I go through depression powered dysphoria episodes regularly over lots of things, weight, voice, neck, face, exc. Mirrors are the enemy.
on the other note of the thread, I knew a trans guy a while ago who referred to that time of the month as, Estrogen Poisoning or Monthly Estrogen Poisoning.
