The best way to find peace in any situation, is to give it up. Just let go of the thoughts, feelings, frustrations and worries. Nothing you can do will change the situation, so it doesn’t make sense to dwell on it and continue to cause stress for yourself.
At the end of the day, what happens in your life is not up to you. As much as we have the freedom of choice, we would all be better off to consult with God and have Him guide our decisions and direction. He already knows the desires of our heart and He wants to give us that and more…if we just let Him.
