Me when I was ill. So forgiveable that people couldn't always grasp what was really going on for me. Acting skills sometimes are useful but at other times it's better to be real and let people share your reality. Give them chance to understand it.
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.
If you want to be with someone and you love them, tell them. Love everything about them even their faults and imperfections. It's what makes them better and unique. It makes them stand out from everyone else. Let them know you love them they way they are.
