I just came across this community. I have no diagnosis and don't seek one. But I wanted to share what has always led to my own personal interest in the subject.
To me the lower-case 'f' when written in a typical way makes me sit there and think, "what a pompous ass that 'f' is", every time. When I write it I have to make it either angular so it resembles an upper-case 'F' (to which I have no reaction) or I have to give it a tail. Otherwise I can't really look at it. For whatever reason, as well, it is only when it is hand-written.
I've never told very many people this, but I thought if I was going to share it anywhere, this may be a good place.
