Not providing healthcare when financially able to, is neglect. If they were neglecting your healthcare, chances are, they were neglecting you in other areas also, even if just emotionally.

I was neglected and ignored growing up and asking for help is one of the hardest things in the world for me. I understand where you are coming from. You also learn how to communicate from your parents in your childhood, if there was very little to no communication in your family, that is probably where your difficulties lie.
