AITA for not talking with my mom after we had a dispute?

Edit: typed this up at work, so it’s gonna be edited to look nicer and give some more context

For context I am 19M full time in college and starting a new full-time job and I am trying to be a bit more responsible.

So this weekend started off normal, going to work at my job a 10-5, which went well honestly. I had planned to game with friends for one of the last times before spring break ended for college and we all got busy again, but mom had other plans apparently.

I had gotten home, and not even 5 minutes to settle in, and my mom tells me to unbraid my hair so she could braid it. Not asking, demanding. I explained to her that taking my own hair down strains my arms, and that they were already somewhat strained from work. She then complained saying that it takes not even an hour to do it, so I gave up with the argument and went to my room to take my hair down.

Before I can even start on the first braid in my hair, she calls me asking about my medication not being picked up yet. I had explained to her that I wasn’t notified of it even being available but I’ll go pick it up, I was honestly happy it was available, but the happiness turned to annoyance as she began using a tone that felt like a playful but degrading and added my dad to the conversation. So now I’m in my car driving while on call arguing with two parents about why I didn’t pick it up earlier in the week. I explained to them that mom had kinda coerced me into switching pharmacies last minute and then calling last minute to make it a 90 day supply which wasn’t easy, then she also had me change pharmacies(I’ll put here the previous pharmacy was 30 day supplies, and had a tiny copay vs this one which was 90 day and free. I don’t dislike the pharmacy but I do dislike the last minute switch when we could’ve switched a long time ago when I got my last prescription). I couldn’t even get the meds because the pharmacy was closed when I got out of work apparently.

I get home annoyed that I’ve just wasted hours and gas of my time arguing and going on goose chases for meds. I get a portion of dinner and she told me I don’t have to take my hair down. I said a somewhat snarky comment under my breath, nothing directly to her. She heard it and decided to mock what I was saying as she just walked away. We haven’t talked to each other for 2 days now. She basically completely blocked me out basically. Am I the Ahole?
