i discovered that wikipedia page when i meant to look up APD (avoidant personality disorder). not too far off from SA either of those. anyways i don't think i have it, but i do think that i have some of those symptoms as a result of social anxiety. i think those symptoms sound very similar to ADHD characteristics too.
I don't exactly know what this Central Auditory Processing Disorder is, but i could well have it. I can tick all the boxes you listed except for the 'behavioural problems' one. I'm a relatively fast typist, but I also spend a lot of time fixing up my sentences and re-wording things. This may stem from my perfectionist tendancies, but i can identify with some of your problems.
I'm up to my second blood test in a week, so hopefully soon I shall find out what's wrong with me. By the looks of things, all my social problems may be a result of hormonal complications.
