i received this as a chained letter a while ago and liked it a lot. i saved it so i can come back to it when i feel these "nots" begin running through my mind, take over my life and create knots in my stomach and in my heart. this prayer helps me focus on who i am rather than who i tell myself i am not. it is also a reminder to think about everything i've got done so far, how far i've come.
i hope it will do the same for you.
