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. You made it, another day. And you can make it one more. You’re doing just fine.
Sometimes it takes time apart to regain appreciation for someone you may have taken for granted. I can definitely say that the grass is NOT greener on the other side... Open your eyes to what is right in front of you. :)
