My parents ???

they always seem to be on my back. My little sister is a compulsive liar, she is 12 & it stresses my mom out & my dad gets angry i honestly think that he is bipolar but he does have anger problems lately he has been really cold to me i dont even want to talk to either of them anymore. Me & my mom are close but now she just annoys me my dad is being a jerk and i cant stand him he says my problems are crap & he doesnt want to hear about it when he is the one who asked me in the first place & it just got thrown right back in my face. He is like a stupid little kid that keeps picking at a scab it starts to heal & then he tears it right back open me & him will be doing ok & then he turns into a jerk again. i cant stand it anymore im frickin 16 almost 17 & im fed up with it i know he is my parent & he provides for me but he is one of the reasons i have low self esteem & confidence i go to school & i hate it but im upset because i dont want to go back home & deal with my family. wat do i?
