After knowing where inferiority come from you might have already guessed what should be done in order for you to get over it.

The person who neglected you might have been severely depressed or mentally unstable and thats why he did so. In all cases there is no excuse for dealing with a child in a bad way except having personal problems that get reflected on the child. In short, you werent treated badly because you were worthless but you were treated badly because you met sick people.
You are not your past: The inferiority complex you are feeling now is a reflection of the inferiority feelings you experienced as a child. Things are different now!! You are not that helpless child anymore, you are a strong adult now and there is no reason to feel inferior because of your past, in short you are not your past but you are someone else now!!
