This girl doesn't have komyushou at all. She's entirely capable of interacting with people.
That it terrifies her to do so is entirely normal given the consequences.
The Mixer is probably the closest we have to evidence that it's not all in her head, as there would be no reason for her to have been placed on the male side if it was.
@Lilliwyt Yes she did ask, what I'm saying is that if the Yuri was all in her head then why was she placed on the Male Side. there were 4 women (including herself) and 2 men.
@GraniteFish@Lilliwyt I wonder if she has any male friends. I'd love to see what guy's general opinion on our little komyusho yurikemen. Whether she's treated as one of the guys or one with envy. Heck I'd wager a guy is her only friend because every other female has been trying to get into her pants
@Lilliwyt No, it's definitely the girls who brought her and put her there. They claim they have not enough people to make it even, and she naturally assumes that there is a girl missing, so reluctantly goes along to make for even pairings. But they deliberately "trap" her being uneven the other way around - there's not enough guys ... so they put her with them, as planned.
