If you feel something, you feel it and it’s real to you. Nothing anyone says has the power to invalidate that, ever. No one else lives in your body. No one else sees life through your eyes. No , one else has lived through your experiences.
And so, no one else has the right to dictate or judge how you feel. Your feelings are important and you deserve to be heard. They are inherently valid and they matter. Don’t let anyone make you believe otherwise.
