Think of your pain like a physical wound. A scab will eventually form to start the healing process, if we keep picking at the scab, it will never heal. Sometimes we just have to let time do its job. The scab will fall off and yes a scar may remain. It may remind you of the past but the pain is gone. And with time that scar too will fade and just become a small reminder from where you came.
The emotional pain may seem daunting at times but Time has the power to heal all things.
