Have you tried reading self help relationship books?

The simplest thing I learned in kindergarten is so true: "Do unto others as you would have others do unto you". That's really all there is to it. And "do" is an action.

When you throw a child into a pool, they will just start swimming (which I don't advise doing literally).

Get out of your parents' house as much as possible. They are strange with this silent treatment and neglect. That's THEIR problem. Find others to fulfill and teach you. Find better role models. Maybe a job where you have a good boss who can mentor you.
