Breaking away from them completely may have been easier for you, but that doesn't mean it was the 'right' or 'wrong' choice. The decision was, and still is, up to you.

I do agree that you can't change anyone except for yourself. I also agree that your family may never change how they act towards you. I'm really sorry you're having to go through all of this alone. How they treated you was completely unfair.

The best thing to do now is to learn to take amazing care of yourself. If you can do that, you won't miss the care you never received from your family. You know yourself best- do something that makes you smile every day. Even little things can help a great deal. If you need ideas, you can google 'self care'. This has helped me a lot, since my family has let me down too.
