Is this understandable?

My mom stacked me in a room with 4 younger boys I'm 15 years old. My brothers are at that age where they think about sex and nudes, and they won't come off face time when I'm changing my clothes. ( cannot change in bathroom ) so I ask my mom for my own room ( there is a extra room upstairs that nobody uses ) but she says no. Every where I go my brothers follow me and I can't even talk on the phone to anyone because they are ESPECIALLY loud when I need silence.  I cut my wrist a month ago because of so much stress going on around the house. The boys are so bad that my mom closes the door when they are annoying and they are stuck with me in the room.
