I'm not kidding here; Your family is not an option.
It doesn't matter if you like it. I don't care if you're happy or think you could be happy in some other situation.
Happiness is temporary, it fades, it's an emotion. Emotions are fleeting. Stand up and grow up. Commit to your job as a husband or wife, as a father or mother, as a son or daughter, as a brother or sister. Be worthy of the family that loves you, and honor them. Love them until you mean it.
