The social stuff doesn't cause me much angst because I am oblivious to much of it.
Sensory issues are fairly moderate-severe depending (severe right now, moderate last week). The more overload I experience the easier it is to overload the next time, the only way to "reset" that seems to be time without shutdowns, which I do not have very freqeuently. Today, overload pushed me to non-verbal, lower reading level, much lower expressive writing level. In the last case I lost access to my "phrase bank" and was barely able to write anything that I wanted to write or that made any sense to me. Right now I am not really back to where I was, and not sure how soon I will be.
Executive function issues are also fairly severe, and explaining them to my therapist was one of the primary reasons my therapist suggested I look into support to assist me with activities of daily living. They are not so severe that I cannot bathe or feed myself Eating is complicated - I've learned how to handle that living here, but if I move I'll probably lose a lot of that as it depends on structure and support provided by other people). That is in terms of knowing I should get food to eat and when. I have issues with most everything. I recently committed to doing more chores around the house, but those chores have apparently made it harder to keep up on other things I do, and I do not know how to balance things so everything remains doable.
A big part of my executive dysfunction has to do with inertia. I get stuck doing a thing and don't eat, don't go to bed, and don't do others I should do. It renders everything more difficult, no matter how satisfying indulging the inertia (or perseveration if that works better) may be.
Sensory issues make it hard for me to function on a job or in school, which effectively cuts me off from both an education and from gainful employment. Executive dysfunction makes it difficult for me to organize sufficiently to get into school or find a job in the first place.
I think I'll pick sensory, because executive dysfunction does have some working coping mechanisms and treatments I can fall back on.
