There's no right or wrong way to feel; you feel what you feel! It would be nice if your family were all friendly and helpful but they are not, they are struggling with issues of their own.

Now you are older, you have to get a place of your own somehow and figure out how to live your own life without hoping they'll change and make room for you in theirs.

Or, you do the best you can in theirs; not confront other people in their own space (if it is your sisters' apartment, one of them not paying the rent means they lose a place to stay and, since it is their responsibility, they're allowed to mess up their own lives by putting horses before roofs over their head all they want and unless your name is on the lease, you don't really get a say?) and pull your weight toward expenses and chores.
