All right, I’m not very good at answering broad questions like this, but I’ll give it a try.
I was actually diagnosed with Asperger’s syndrome back when that was an official diagnosis and was never given a “level,” but based on descriptions and the fact that there seems to be a big difference between me and many “high-functioning” people, I’m guessing if I was re-assessed I’d be diagnosed with level 2 ASD. Not entirely sure what’s because of my autism, what’s just me, and what might be due to something else, though.
Let’s see, biggest differences... In my social skills group, where most of the participants seem to be “higher functioning” than me, I’m the only one who obviously stims the whole time. People almost a decade younger than me already have jobs and are looking at living on their own, but it’s entirely possible that neither is possible for me, making a lot of the stuff they cover irrelevant to me.
I have selective mutism, which I think is probably tied into the autism/social anxiety - actually, it feels like I have two different ways of being unable to speak, and one is more like extreme social anxiety, where I get so nervous I’m literally incapable of forcing my vocal cords into action, and another where I pretty much can’t form a coherent sentence even in my head, which seems more like an autism thing.
Sensory issues are a
huge thing for me. I have major issues with getting wet and with getting out of water I’ve been submerged in long enough to get accustomed to it. This includes baths and showers, I use a wet washcloth and soap for my body and my mom washes my hair in the kitchen sink while I mostly shut down because of sensory overload. I end up mostly to completely shut down every time I go to a store or restaurant because of overstimulation, although now I have a service dog who helps that not happen so readily. In college, the fire alarms in the dorms were so horrible with the noise and flashing lights (and crowds of people as everyone poured out of the building) that I’d still be shaking half an hour after we were let back in. Late summer is horrible for me because of the cicadas, they are annoying at best indoors, and if I’m foolish enough to step outside while they’re busy buzzing, it is literally painful even with covering my ears or wearing noise-cancelling headphones.
On a related note, I’m also completely incapable of filtering out “background noise.” Every noise requires just the same amount of attention as far as whatever part of my brain is concerned, and I can’t convince it otherwise.
Speaking of attention, I’ve recently realized that I have an overwhelming need to know about absolutely
everything about what’s going on around me, which I typically use my hearing for (except in a car, I’m watching out the window as well as taking in what’s happening in the vehicle - that’s part of why I really don’t think I
should drive even if I
can eventually get a license, because my brain can’t just focus on the road and “tune out” everything else outside, it’s all equally important to my brain and it
will focus on things it shouldn’t be while driving no matter what I do. ). This means if I try to use earplugs or noise-cancelling headphones to deal with noises that are a problem for me, I usually freak out because I can’t monitor my surroundings properly.
I also have trouble keeping up with daily tasks like brushing my teeth, cleansing, and even eating. And I have an annoying tendency to just turn alarms off, go back to finish up what I was doing, then forget that I was supposed to do whatever the alarm was supposed to remind me about, so they don’t work reliably for me.
That’s what I could think of off the top of my head, I’m happy to answer any questions about this or anything I forgot to cover
