I'm not sure which is worse, really.
Not coming out and facing the dysphoria and lots of people I care about not really knowing me properly and misgendering me constantly without malice, and not knowing how anyone would respond to my potential transition, and always having the possibility of transition there taunting me?
Or transitioning, and constantly either being under threat or being worried about the possibility of being under threat, and possibly losing friends for it?
I think I'll just go with the safe option of doing nothing and hope I'm not making a mistake.
