I am beyond frustrated

I need to get fully independent from my parents and this is taking way tooooo long. I am tired of them referring to me as a liability. I do my best to not ask them for anything!! The sad part is that when I do need help they get mad. I do not want to ask them for anything every again in life. I do not want to talk to them about my life or what happens in my life because they are insensitive and rude. They believe that they know what is best for me because they know me so well... because they have been "there" but... they have NOT... I am not a younger version of them.
