As you mentioned not brushing your teeth daily, I'd like to point out that could be down to your depression. Back when I first had to give up my job, I was very deeply depressed and that led to me taking very bad care of myself. It's only since the depression lifted a bit that I've gotten self grooming back into my daily routines.

Like the others have said though, you don't have to have every symptom of autism/AS to be on the spectrum. I do follow routines and I become very upset if there is any disruption to them, though I don't follow times just events.
