How to make depressed dad happy?

my dad is so strict he once got mad because someone threw away a half eaten donut. i thought he was a jerk until i hacked into his facebook account (i know i know he needs his privacy i do feel bad about it) and found out hes a weirdo no one wants to talk to, like he'd send 3 messages to someone and they wouldn't reply even if he asked them questions & even if he was polite some people said stop messaging you freak. now i know hes just taking hes frustrations out on me and my brothers. i want to make him feel better even if he can be a jerk. im already cleaning the house and talking to him more often any thing else i can do btw i cant spend money or drive him places cuz im broke and im 13
