When you’re tired and worried, sleep.
When you’re hungry and worried, eat.
When you’re bored and worried, have some fun.
When you’re overworked and worried, go home.
When you’ve got a headache and you’re worried, find some pain relief.
When you’re lonely and worried, talk to someone.
One of the best pieces of advice I ever got about being worried, overwhelmed, stressed, or anxious, is to deal with the other problem. You probably can’t fix the overwhelmed part when you’re sleep deprived.
One of two things might happen: You might wake up feeling refreshed and ready to deal with your yucky feelings. Or you might wake up worry free and realize the yucky feelings were just there because you were sleep deprived.
