why me

my family does not understand me but they use me and treat me like Cinderella. I am tired of being the only one who does anything around the house, taking care of mom's dogs (even though it is her business). I feel like I am all alone with no one to turn to for help. I don't know what to do, but I am so exhausted and tired of not being able to do anything fun. I don't know what to do.
