Hey buddy, since you haven't finished college yet, you have something to look forward to in life...like an aim or something. now just focus on getting your family out of this financial fix. How does your dad still stay here, if he has no work? He also doesnt need much education to find a work that can pay enough to buy food for the family, i believe.
and i don't think you should shoulder the situation all by yourself.. you must work out a solution with your dad... or you will end up blaming him for the rest of your life.. for having ruined everything.hope you get what i mean..and dont worry, everything's gonna change.
