AITA for refusing to tolerate my roommate’s mess after they left dishes and trash during Thanksgiving break?

So, just for context, my roommate "Britney" (21F, fake name) and I (21F) have been friends literally since kindergarten. We grew up in the same neighborhood, went to the same schools, and even ended up choosing the same college. We have been roommates in the past but year we decided to get an apartment together.
And let me just say… this apartment is nasty. Not because of me, but because Britney absolutely refuses to clean. She has never liked to take the trash out. Which causes an ungodly scent I think it comes from her throwing the raw packaging of meat into the trash and just leaving it there. The smell sits it is horrible it’s embarrassing to have company over. Sooner or later I end up taking out the trash because the smell is unbearable. I have spoken with her about this and she take it out for the time being and then it’s goes back to me taking it out .

But the thing that finally pushed me over the edge was what happened right before Thanksgiving break.
She made soup Thursday evening, which is fine. She left the leftovers in pot on the counter. I didn’t think too much about it because I thought maybe she had stuff stuck to the pot and was letting it soak and I figured she would wash it before we all left for break.
I wake up Saturday morning walk into the kitchen and I see the pot on the counter and dishes in the sink. Also she is gone, we live about four hours away from our college town, and when I check her location she was already at home. she had a whole journey ahead of her and still didn’t bother cleaning a single thing.
And when I tell you the place looked disgusting:
The pot of soup was still there, untouched.
Her dirty dishes were still piled in the sink.
Garbage was overflowing.
There was literally a pile of trash in the living room.
The apartment smelled like poop…
And who do you think cleaned all of it?
Me.
The truth is, I felt like I couldn’t sit in there or even breathe until I handled it. It’s giving "I’m your mom," not "we are both grown women living together."
I did not want to spend the start of my break cleaning up after someone who has been my friend since childhood. And honestly, I love her, but this is making me resent her deeply. I have not confronted her yet because I am pissed and do not to blow up, but I am so irritated and trying to figure out if I’m overreacting.
