Independent or Prideful ?

So I've just graduated high school a month ago & throughout high school, with the exception of my senior year I've held a job. I moved out my mother's house into my dads, that's when I had to let go of my job. My dad still looks at me as if I'm still five years old. (A huge pet peeve of mine). Weeks after graduation I decided to leave the state without telling anyone, but my mother found out. So I ended up going back home. Basically I'm always reminded of my age & that I have to depend on others around me. At this point of my life I really just want to shut off all & any help, with the addition to cutting off my family. I know what I am capable of & of course I'm scared of failing but what would life be without hardships? Am I trying to gain my independence or am I being prideful & immature?
