Is it normal to resent my own mother?

I resent my mother in more than one way. I hate the way she speaks to people. Treats herself and my sister highly and treats me and my dad like absolute shit. I have a theory that she may be Bipolar because she will talk kindly to one person, turn around to talk to another person and be completely rude and disrespectful to them (It's usually me) I don't feel her punishments are valid or reasonable. (Taking my phone because I had no phone service to answer her call) I just think everything she does is completely fucked up and I cannot wait till I can move out. To be honest, is it normal to resent my mother?
