[Thirteen]

Sounds like Major Depressive Disorder to me. I mean, sometimes when people are very depressed, they can't cry, and go almost numb.

Perhaps this is something to talk to your doctor about, but I highly doubt it's anything close to being a sociopath. Just because what you're saying doesn't sound symptomatic of a sociopath, at least, not to me, but I'm not an expert.

My friend, however, dated this girl he was 99% sure was a sociopath, and it's rather tricky to explain. And I know he'd probably tell you the same thing I did, that it sounds like Major Depression.
