Name this Thriller/Horror from the last 6 years

I simply cannot find a movie I swear I’ve seen within the last 5 years. I asked chatGPT and nothing. I only remember bits and pieces but it’s eating me ALIVE.

Here’s what I know:

The protagonist is a brunette younger woman that is living luxurious home with her boyfriend, who is wealthy (possibly an actor?). It is modern time setting. She starts to experience terrifying visions and becomes increasingly paranoid. I believe at some point she realizes that she has been manipulated by her boyfriend and his rich circle of friends, who are mocking her for their own amusement. Possibly drugging her? Or she has previous ptsd and they are triggering her? She loses it at the end once she unravels what’s going on and I believe ends up killing everyone at their home?

I thought the main actress was Annabelle Wallis. I also thought it was the movie Malignant(2021) but I recently rewatched and it was not what I remembered. This is what sparked my questioning (and sanity)

Sounds wack but this is all I know. Maybe I’m mixing up multiple movies into one. Either way, SOMEONE PLEASE TELL ME YOU KNOW WHAT IM TALKING ABOUT. Or maybe I’m the one having visions now. Plz and thx
