I have quite a few different types of synesthesia, one of which is graphemes-color.
My personality.. I'm an extreme introvert, I guess. I dislike pretty much any and all face-to-face social interaction. Loud people bug me very much. (People in general bug me very much.) I'm still living at my parent's house (I know, I'm such a winner
) so I can't answer the third question. Though, when I did get my first job, it was kind of a shock. Not really that profound, though. It was just sort of like "oh, wow, this is all new to me." Graphemes-color isn't "overwhelming" to me, though the combination of personality-color, personality-taste, and personality-texture that i possess is really
overwhelming in crowded places or when I'm around people I'm not familiar with. Never really had much of a problem with graphemes-color, though.
I know this post is really old but I just thought I'd contribute. Good luck in college.
