Stop worrying.
Stop getting angry at things that aren't worth the energy you put into staying angry.
Take a shower.
Take five showers.
Hell, take ten showes if you want to.
Stay in bed all day and do 'nothing'.
Watch sh*tty romantic movies and cry your heart out.
Stay outside all day.
Wake up in the morning with the determination to fall in love with your city all over again.
Find quiet cafes and independent bookstores that you've never come across before.
Pretend you're a tourist and take photographs.
Stay out all night.
Do things.
Take care of yourself.
