Welcome! You might have already considered this possibility, but as you don't mention it, I'll throw it out there because these things on your list caught my eye. Emotionless Anxiety/SNS overdrive No libido Light/sound sensitivity Allergies I was just reading a random website I stumbled across (http://www.mthfrheds.com) and the website owner believes he has found a genetic link to many of his family's ailments, which include dysautonomia, Ehlers-Danlos Syndrome, and autism. These things I pulled out from your list CAN be associated with autism and autism-associated sensory processing disorder. I understand that the disorder forcing you to be homebound and unable to move about as you desire causes depression, but I also see a decreased desire for social interactions with others expressed in your post (when friends force me...). Many normal introverts would identify with a decreased desire to go out and with getting overwhelmed in social situations and needing time to recoup adter, but so would many with autism. The more severe forms of autism, which are often also associated with intellectual disability, usually get the media publicity, but there are many high-functioning individuals like doctors who are also on the autism spectrum. Allergies, asexuality and/or no libido, sensory processing disorders, and feelings of being overwhelmed are also common. They aren't symptoms of autism itself, but they are not at all uncommon with it, either. Having autism is also a potential explanation for why you believe you were born this way. Is it possible that you're facing both autism and dysautonomia? Here's one rough screening test. it isn't diagnostic, but it can point out if you're strongly leaning one way or another: http://www.wired.com/wired/archive/9.12/aqtest.html
