Hi GypsyRosalie

I am not a therapist so I will take a stab at this. I have read that people with autism and ADHD have problems with certain stimuli such as the feel of certain fabrics and I am sure there are other sensory sensitivities. Here is an in depth article on autism that may help.

Autism Spectrum Disorders In-Depth | Psych Central

Since you have already been diagnosed with DID and GAD, it could also be part of those DX's. I would bring this question up in your next appt with your treatment provider. Hope the article sheds some light and helps answer some of your questions. Best wishes.
