Am i being irrational ?

So, i would first like to start off by saying that i don't have a hard life. My parents do a lot of things for me. They pay for my school tuition, books and transportation, they give me spending money, and take me on vacations. Although i constantly feel like they think because they do so much good, that the bad stuff they do doesn't matter or count. My father is constantly in a bad mood towards me, anything he says to me is negative, or being said with attitude back towards me. He treats me like I'm one of his buddies and just because he thinks I'm "tough" he thinks its okay to talk down at me and constantly snap. I try to tell my mom about it but she seems to just brush it off like its not big deal because "thats just how daddy is." I am sick of constantly feeling like a lesser to my older brother which my parents, well mostly my dad, puts on a pedestal. I feel like I'm always an after thought and just someone to put down to make them feel better. I am a good kid, i go to school, have a part time job and have a good head on my shoulders. So i don't understand why i am treated like i do bad things. I always had thought that fathers are supposed to treat there daughters with trust and respect. All of this stress is causing me to seriously dislike my parents and hate my life. So my question is: Am i being to sensitive and irrational, should i suck it up and just deal with it?
