Dear inner child,
I'm sorry you always felt so alone. I'm sorry you constantly felt like you had to "deliver" on appropriate behavior, or risk being shunned. I'm sorry you were being shaped and molded into something you're not. I'm sorry it's so hard and scary and lonely to fight free of that mold now.
I'm sorry there was never a single person who accepted and loved you for you. I'm sorry for the damage it's done to you as an adult. How compliant and scared it has made you.
Again: I'm just so deeply sorry about how alone and to the core rejected you've felt.
