Just laugh. Laugh as much as you can. There are so many funny, silly, and goofy things that happen throughout the day. Laughing makes everyday so much better.
laugh out loud when you find something funny, don't deprive yourself of the LOL. When I laugh at random times my friends just say 'oh, don't mind her she's just open laughing', you can open laugh too, it's fun, you'll feel better.
