Heart, please heal.
You don't protect your heart by acting like you don't have one. The same walls you built to keep the hurt out are the same walls keeping your blessings out. Let your pain make you better and not bitter. Stop taking everything so personal. Decide to see things on the happy side instead of the hurtful side. Hurt people HURT people. Healed people HEAL people.
"For if ye forgive men their trespasses, your heavenly Father will also forgive you."
