Letting go is not just a saying but it is an action. You have to mentally and emotionally let go of whatever is holding you back. You will feel the heaviness lift off of your chest and shoulders. Let go of all the hurt and pain and forgive those who have done you wrong. Live your life for yourself not through hurt and pain. Start off new today. Wake up, shake it off and keep it moving. Letting go is the most rewarding thing you can do for yourself. It is not easy and it will take some time but make sure you at least try and take it day by day.
I encourage you to set yourself free of all hurt and pain! Forgive others, keep pushing forward and let go of everything that is not valuable to you becoming better!
