Help, I really don't want to share a room with my mom!?

My parents are getting divorced and that means that I have to sell my house. My mom wants me to live in a one bedroom apartment with her temporarily until we find the right home. But who knows how long that will be. I'm a 17 year old girl and I want my privacy. I know that is it going to annoy the living **** out of me. My mom and I have different life styles and waking hours plus she likes to spy and see what im up to a lot. I've told her that I really don't want to share a room with her but she doesn't care, she just gets mad. I'm 17, im still growing, im going through tough times, I've lost everything I've cherished emotionally and the least that I would want is my privacy and dignity taken away from me. Help what do I do, I can't reason with her.
