How do I stop being as close with my mom?

I guess because I'm a teenager (just turned 16) I'm experiencing that phase where I think my parents are a nuisance, but everyday my mom is just becoming more and more annoying! I'm starting to realize how narcissistic and dramatic she is and I really don't want to have to deal with that anymore than I have to. But she always tells me about her problems any chance she can get (in the car going somewhere, sitting at home watching TV, while we're eating, etc). How can I distance myself from her? Thanks for helping!
