My grandmother once gave me a tip:
In difficult times, you move forward in small steps. Do what you have to do, but little by little. Don’t think about the future, or what may happen tomorrow.
Wash the dishes.
Remove the dust.
Write a letter.
Make a soup.
You see? You are advancing step by step. Take a step and stop.
Rest a little.
Take another step.
You won’t notice, but your steps will grow more and more. And the time will come when you can think about the future without crying.
