AITA for snapping at my friend and telling her to stop commenting on how I eat?

I've been close friends with "Chelsea" for over 10 years, and until last year she had never made any rude comments towards me or anyone that I'm aware of. Neither of us are confrontational people (I try and avoid it at all costs if I can), so we'd never had any big arguments or falling outs.

Sometime last year however, whenever we would meet and get something to eat she would make little comments towards me and it would really annoy me. Things like "How do you even eat that much?!?" if I got a large meal instead of regular, or other passive aggressive (?) comments like "I've only taken one bite and I'm already so full, idk how you do it." They rubbed me the wrong way, but not wanting to possibly start an argument or seem sensitive I just bit my tongue.

Well last month we met up, along with a friend of hers that I had only met once before. We went to a fast food place we frequent a lot, she and I both got the same regular meal and sat down to eat. I finished the meal in about 10-15 minutes (which I don't think is that fast for a burger and some fries but idk lol), when I finished she looked at me in shock and went "Oh my god are you finished already? Jesus Christ!" in a really overexaggerated surprised tone.

That was the kicker for me, especially when it was in front of someone I barely knew, I replied "Well I'm sorry I'm not some dainty princess who takes a whole day to finish a single crumb! Maybe if you spent less time commenting on how I eat you'd be able to finish your own food quicker, acting like the fucking food police." They both just looked at me in shocked silence (I was just as shocked as they were tbh), I got up quickly because I could feel tears in my eyes and left. In all honesty I expected her to message me later and apologize but she didn't, and I didn't feel like messaging her first.

We haven't spoken since then and I'm starting to think that I shouldn'tve reacted the way I did. I don't see why she'd go out of her way to upset me so I've realised now that I overreacted but I'm still pretty upset with her so idk what to do.

To clarify, I eat normally, mouth closed and everything. And I don't shovel food in my mouth. I'm slightly chubbier than average but I'm not overweight and never have been. I also have an ed, which she knows, which is why any comments on my eating habits bother me so much.
