This is both a plot point and something that will effect the main character so to hedge my bets I decided to post it in General. My character feels that their 'mental me' doesn't match their 'physical 'me' and that is about to be revealed. Now the obvious one to go for is Gender Dysphoria as i imagine it's the most extreme example, but at this isn't really a LGBT story I thought I'd see if there were any other options before I went down that route. So does anyone know of any other conditions that can lead to this feeling? Preferably of an extreme nature but with no obvious external signs (assuming the character hasn't done anything about the feelings as yet).
