I Shut My Self Off To People

There are times that I shut my self off to people. I don't mean to at times. Its when I don't feel like talking. I need to have some time to my self. I just wish that my mom wouldn't bug me at times. I don't feel like talking to her at all. I don't mean to look like that I am hurting. When I'm not hurting at all. I just feel like that I need some alone time. That is all.
