My mom is going to kill me helppp!

I recently opened a Facebook account for yaoi related things. My phone gallery also has some yaoi photos. I also somehow allowed notification from a porn site idk how I don't even watch porn. I jokingly searched it up with my cousin. Now notifications from that site on my phone and I can't turn it off. My mom found out. She slapped me and yelled at me a lot and told me I could get lost from her house. She is a homophobe and a very religious muslim women. Now she probably thinks I am lesbian (I'm not) and I watch porn (I don't). She is probably never giving back my phone and keep a close watch on me. I won't be able to read any manga or watch any anime, movie or show or even just use phone or laptop cause she will be watching.( I am writing this on my laptop currently because she is sleeping and I have online classes) If this continue I will go mad. I don't even have friends to spend time with.
What the hell should I do pls helppppp!（/TДT)/
