I forget people when I can't see them. Including friends and family.
Poor object permanence is a ND thing apparently, and it extends to people as well as objects.
I am very fortunate that I have really understanding friends but it certainly took a long time to find my tribe.
Also a lot of diagnoses. ADHD, ASD, Dyspraxia, Hypermobility, CFS. I have found that the people who want to remain friends with me have all taken it upon themselves to really understand my disabilities and they appreciate what I do bring to the table rather than what is missing.
I also bite my nails, pick spots, pull hair out of my head, pick the skin on my feet until I can't walk and/or hobble until I can't feel the pain anymore. It really disabled me when doing some long retail shifts.
I have tried so often to wear fake nails but they feel so alien, the picking starts immediately and they're off within a day.
It's taken me 3 years to grow out the bald patches of my hair on my head, but I have redirected to hair on other parts of my body.
I often feel like I'm the only person going through this but I know I'm not, rationally. A lot of people just say well have you tried not doing that, and it's just so difficult to explain the lengths at which I've gone to in order to not do the things I do.
