A time to let go, the question of "FAITH"

How do you know when it's time to let go? most of the time one runs out of answers and prays for a miracle. We all need angels to guide us through life, in good and bad times, so for today my prayer is for the good Lord to guide and give me the courage to get on with life with resilience and optimism. I pray that my FAITH in GOD remains intact because I know that GOD has a purpose for me in the world, and that my attitude towards life reflect and affects all those close to me and to each and every individual I come across through this journey of life.
