Blah - Who Needs a Normal Family?

What do you do when your mother lies to you to protect one of the "chosen ones" (a favorite child)?  Being talked to, lied to, like you aren't smart enough to know already, is a bit degrading. 
I hate the dysfunction of our family and I am sick of the favoritism to some and disrespect/meanness directed at others. Mothers aren't supposed to be like that. I can not ever seeing me treating any of my children that way.
