Take a shower, wash off the day. Drink a glass of water. Make the room dark. Lie down and close your eyes. Notice the silence. Notice your heart. Still beating. Still fighting. You made it, after all. And you can make it one more. You're doing just fine.
Not everything has to be perfect today you can have days when you feel like shit when you feel strange unsure scared confused and lost - just know that you have tomorrow to pick yourself up again dust yourself off and start over better than before.
