Dealing with toxic mother

I’m 19 years old & I’m really not allowed to go nowhere unless it’s pertaining to work. I feel like i should be able to go out because i do put up money for the rent &buy my own groceries. I paid for my phone and pay my own phone bill. Yesterday, out of no where after we had a good time my mother asks me to see my phone to see my pictures I told her that i haven’t taken any new pictures .. she then says let me take your phone to go through your album. She said she wants to see if I’m taking any inappropriate pictures which I am not and i honestly don’t think that’s the reason why i feel like trying to catch me in something all because she doesn’t trust me. but i am 19!! You can’t do that. I keep asking her why does she want to go through my phone and she just starts screaming cursing saying I’m trying to rule her like what are you talking about? She got so angry as if she wanted to hit me. I tried speaking to her this morning she just completely ignored me. I can’t even go outside for fresh air because im not allowed to leave the house unless i show her my phone.Am i wrong for not letting her go through my phone?

She always have negative energy and i tried not to let it go to me but it’s the worst when I’m stuck in her space which is unfair!
