Strangle her

Yeah... that's not at all a batshit crazy/vindictive thing for her to do... I'd start looking for a new roommate (or new apartment, whichever is easier). If you live in a dorm or student housing situation, report her to the RA or housing authority. Destruction of property is grounds to have her removed.

prank her until she moves out lol

What the actual ****. That is some next level crazy. You need to talk to your landlord and/or dorm room RA. That is a sign of someone who needs to control everything and could very easily turn abusive. You need to get out of there before it gets worse

Well someone's a yandere in the making- and it isn't OP...

Just look for a way to move out or have her removed from the apartment or dorm peacefully.

Replace her shampoo with mustard. Only if you decide to up n leave tho, you don't want a prank war. Other than that I'd invest in some hidden cameras who knows what else this clown is capable of or is already doing behind your back. Good luck OP.

What an entitled brat >:^( I'm hoping you live in a dorm and have admin you can report her to and move. I know first hand with an apartment there's not much you can do besides suck it up or just wreck your own credit by breaking your lease.

Doesn't this sound wrong in her own ears ?
