Family?!???!!??

Family!! What is family can someone explain that to me I'm trying to grasp what is family to me, I try to do what is right by my family but sometimes what might be right for your family my not be what's right by you. You stretch and bend for family because that's what you are suppose to do. But is it wrong for me to expect that in return yes it family but it doesn't make it fair I do a lot for my family but in return I get nothing . I'm very much so fed up with the family is suppose to be here for one another well to be honest I don't see that much happening for me. Am I wrong for feeling this way or is it just human nature who knows but I do know, treat people like you want to be treated.
