I'm like most of you in this regard. I can remain at home in the house for days on end. Sometimes I feel great anxiety at the prospect of having to go anywhere so I try to schedule any appointments far apart so I don't have 2 on the same day or on consecutive days. Fortunately, my husband works outside the home & I don't really have to go out most of the time if I don't feel like it. Since we live in the suburbs & I know this area well (grew up around here) I know the days & times when there are likely to be few people lurking about.
Thankfully, due to the internet, so much of our shopping can be done online. Even the pharmacy provides free delivery & there's a grocery store where most things can be ordered online & delivered. Since, they say, its essential for our ultimate mental health to not become a hermit-like shut-in & get out sometimes, I force myself to get up & go out once in a while. I NEVER just 'spontaneously' lose my mind & decide to go hack around in the mall, but I might do like I did today. I made a short list of a few groceries, picked an off hour when there are usually few people, drive myself to the store, park right near the entrance, go in fast, get what I need, use the self-serve cash machine & return home.
As for the person above who is a university student, many courses have an online option. Also, if yours is a big university, it probably has an access centre for students with disabilities. They can arrange with your professors to have you do the lion's share of your work from home, write your exams in a solitary room or even at home in some cases & NOT have to participate in those group assignments & projects from hell. Personally, I work much better on my own at home. I can set up my workspace as I require depending upon the quirk du jour I'm experiencing. Also, this enabled me to do my work when I felt like it whether that was 4 am or noon. The access centre where I studied really was a life-saver (& a sanity preserver). Being an Aspie really doesn't have to ruin your life or destroy your career options. Many people in my area have a home office (my husband has one) with everything they require in it.
Many NTs are overwhelmed & drained from toxic, loud, crowded unpleasant work environments too. Unlike an Aspie who is more likely to be honest about being overwhelmed, these NTs drown their feelings in a heady mixture of anti-anxiety meds & booze & they plod on until they wind up cracking up. We just acknowledge that we're likely to crack up in a given situation & most sensibly, make the logical decision to AVOID THAT SITUATION!
