She's your mom so naturally she's going to want to know what's up with you. I think you need to tell her what you just said to me... "Mom, I love you and I love talking to you about things, but sometimes I don't want to have to tell you everything. I want some privacy." I think if you tell her that and are honest with her, she will respect that and might not be as nosy. If you keep the communication open with her, you'll have a strong & close relationship as you grow up.
