How do I get my mom to stop stalking my facebook page?

[Why are you reading this]

My mom stalks my facebook page 24/7. I don't have anything to hide, I just want her to back off a bit. I am a very trust worthy person, I get straight A's and I would never friend someone I don't know. My mom checks facebook like 100 times a day and she even gets notifications on her phone whenever I post something. She is even friends with some of my friends from school. Whenever they post something that she doesn't like, she will give ME a lecture. It makes me feel like she doesn't trust me. I am very safe on the internet as well. I don't play any of the games on facebook, or take any of the quizes. My Grandpa and Grandma also moniture my facebook, but of course, they don't do it as much as my mom. One day, I created another facebook account that my mom didn't know about. Soon enough, I had to delete the account because my mom was starting to realise what was going on. Facebook is becoming less fun because I know that my mom is watching me. Sometimes I consider stopping facebook all together. But at the same time, I enjoy talking to my friends on there. None of my friends famillies stalk their accounts!!
