/feels/ - Advice & Venting

I live with my younger sister who is 20. I am 24. She has always had weird mood swings since she was a kid but every since she became a teenager who smokes/drinks/does drugs she goes absolutely off the wall if you tell her something she doesn't like.

for example, if someone asks her to clean something up she will go into a screaming fit, arguing with you about how she already did something a few days ago, or how you're "so fucking annoying and retarded", going around slamming doors and sometimes breaking my things.

If I ask her nicely, she ignores me or tells me to shut up. If I tell her to do it, she flies off the wall. If I wait for her to do it on her own, she doesn't do it.

She says it's "the way I ask her" but when she asks me to do something, and I say no, she flies off the handle too. Recently I told her to stop talking to me that way when she started screaming 3 sentences into a conversation and she told me
1. That I started it
2. That I piss her off
3. That I need to watch how I talk to her and ask her things
I told her it's her choice to get so angry over a simple question and she said it was my fault again.
I know for a fact that I did not raise my voice once when I was talking to her. I specifically kept it down because I didn't want to feel insane again, because these fights always get warped in my memory and she starts using things against me that aren't true, but I can't prove wrong.
Maybe I do have an "attitude" when I tell her? Am I just the mean older sister?

I want to figure out what I'm doing wrong. I don't want to get in fights with her anymore, we're adults and I'm sick of it. I don't know how to predict these moods, and they don't even compare to dumb sister arguments we have. But it's very frustrating that I can't ask her a question if she's feeling "off" because it'll turn into a screaming match.

Is this normal? Is there any chance at having a normal relationship? I don't know any other siblings who behave like this. Some days she'll be all nice and we'll get along fine. Other days are like this and it's tiring. This is honestly just the tip of the iceberg with this dynamic but the most pressing one to me because it's so distressing and just ruins my day, but she gets over it seemingly instantly even though she was hysterical just 10 minutes before. I don't know anymore
