would it be difficult for you to just not let your father treatment effect you? I mean if he is not ready to take care of his own child's problem..you shouldn't expect more. i just suggest you to let it go
forget the past and future enjoy the present. consider you are alone in this world focus on yourself make your friends make a girlfriend or boyfriend
past is past now try to make your present better try to improve your relation with parents better try your best if the things doesn't go right even after trying your best i think you will be proud of yourself that you did your best till end. but forget all this and thing positively.
