Extremely unhappy? Help me?

It seems to me that you are like the black sheep of the family ,because you are unwilling to do their bidding and you being of age and not old enough cause your not 18 yet ,yes they will look at you as being to young ,once you reach 18 then you can tell them (in respect )to them that you can prove that you can be what you want and do what you want and manage without them some day and once things blow over,then go back to them and show them your proof of success.
