My mom is sooooo obsessed with facebook games!?

My mom is so obsessed with the dumb games! She plays them ALL day long! I come home from school and play for like 2 hours, and she calls ME an"addict"! She doesn't believe she's obsessed., she believes she just likes to "play" them. She says she isn't addicted because she still does her around the house duties. Skipping duties comes after you have become a hardcore addict. The dictionary calls addiction "To be a devoted fan". I think she's devoted enough.She complains when she helps me with Homework and any chance she gets she leaves and tells me to look up answers on youtube. How the **** do I do that if she's on the computer! She makes ME feed HER dog and take it out! She thinks shes freakin perfect! She thinks that I'm obsessed when i'm not. I'm a kid for shitsakes! Kids play games! She if forty-one years old! How do I convince her that she has a problema?
