Somewhere between Social Phobia and Avoidant Personality Disorder. Not sure exactly which one.
And there's definitely signs of Obsessive Compulsive Disorder and Blushing thrown in, too.
If you want to get technical about it, there's signs of numerous other disorders, too. Probably the only disorder I don't have any sign of is the type of schizophrenia in which you see things/serious delusions.
