Update:

I managed to score a ticket to a concert last night so I was able to get out of the house for a few hours while my housemate had her band practice.

She said it would be acoustic but there were drums (sneaky). There was also a random dog that my housemate hid in her room but it kept barking and howling.

When I came home around the time I said band prac needed to be wrapped up they were still practicing and the dog was still carrying on. Then they started a bonfire in the backyard and had a social gathering. Many people stayed over. I didn't expect any of that.

I managed to fall asleep around midnight and now I'm at work early because we're insanely understaffed and there's a lot of responsibility put on me.

I'm just so upset I tried to set a boundary and I was so proud of myself but it was for nothing.

She's even given us a heads up about ANOTHER practice on Sunday. This one will have amps and drums and she couldn't tell me when it will wrap up because technically her sister is organising it.

FFS. I feel like a POS.
