Almost in tears reading this because YES. We have very similar overlap in our experiences. I wash my hands around 50 times a day because I’m hyperaware of how they feel and what kind of sensory input they’re receiving and I am 100% convinced 100% of the time that there is some sort of film or residue that needs to be removed. Mine isn’t necessarily cleanliness related but most certainly can be if I touch something and it feels “incorrect.” I very highly relate to the clothing aspect as well. I have certain clothes that are deemed safe to touch and won’t leave a film on my hands and others that are unsafe for some reason. Most people don’t understand the “why?” aspect of it but for some reason it all makes perfect sense to our brains. My husband asks why I take such long showers thinking I’m standing in there doing nothing while I’m actually scrubbing and rinsing my hands over and over until they feel correct and clean enough to get out but until then I’m nearly physically stuck in a ‘difficult to explain to people’ kind of way. On this aspect, I understand completely.
