AITA for basically calling a girl ugly when she kept pressing me??

I’m pretty sure I’m the asshole here because I feel really bad because I realize that I shouldn’t have commented on appearance of a girl around my age who might be sensitive to that

Also for context I’m lvl 2 autistic (diagnosed) so I sometimes act odd in public without realizing it in the moment

So I (18F) was at a sports bar/restaurant with 2 of my friends and my brother, and at the end of my meal, I kinda did a side laying down position at the booth because I was extremely tired, but then I realized it was a bit inappropriate to do that at a restaurant so I sat up and laid my head on the table.

For context, I was wearing a skirt but was wearing obvious shorts (they were puffy and shit) and when I was lying down my head, I heard a voice so I lifted my head thinking it was a staff saying “you can’t lay down here.” (Fair enough) but then it was a girl who was also a customer that was in the booth beside us, and she said “why are you showing your ass, that’s embarrassing,

That’s disgusting, why don’t you have self respect, we can see your underwear” over and over and I said “I have shorts on” and she said “they don’t look like shorts” so I said “well I don’t know what underwear you wear but these are shorts.”

And then she went on her rant again about how I have no self respect and I’m disgusting, while her boyfriend tried to get her away, and so I said “I’d be disgusted too if I had to look at the mirror and see that everyday.” And then she did a quote thing with her fingers and said something but I couldn’t hear it and then stormed off. But my friends were also backing me up and saying “mind your business.”

Now looking back, I shouldn’t have commented on appearance but I was so anxious and embarrassed in the moment and just saying whatever came to mind, also for context I think that girl was drinking too because I saw her have a drink of some kind earlier, and i think maybe she was upset because she thought I was showing my ass with her boyfriend around but I wasn’t.
