I wrote a few games about emotions - if you're sad or angry. I find if I'm holding in an emotion, the games help me to release it. So use them as an idea for your own game. For example, if you're feeling sad, write a game about consoling someone. If you're angry, write a game about getting even - or a game like whack-a-mole and pretend the mole is your ex. Or do the opposite and write a game where you must make everyone happy.
