My father is an ex hikki as well as a current hermit so I've probably inherited his taste for solitude. However to my knowledge he's not a schizoid, whereas I am, perhaps making me an example of how kin commonly amplify the behaviors learnt from their parents?
Regardless; what are you trying to break free from? Learnt asocial behavior or your familial expectations of asocial behavior?
If it's the first: learnt familial behaviors are quite difficult to overcome, if not impossible to overcome fully, however really the only way you can improve your social prowess is to force yourself to be uncomfortable in any social situation.
