I am pretty sure this was posted somewhere on MB before, but it bears repeating and I think is really good advice. I know I am trying to live by it.

Let it go
By T. D. Jakes
There are people who can walk away from you. And hear me when I tell you
this! When people can walk away from you: let them walk. I don't want you
to try to talk another person into staying with you, calling you,caring
about you, coming to see you, staying attached to you. I mean hang up the
phone. When people can walk away from you let them walk. Your destiny is
never tied to anybody that left. The bible said that, they came out from us
that it might be made manifest that they were not for us.For had they been
of us, no doubt they would have continued with us. [1 John 2:19] People
leave you because they are not joined to you. And if they are not joined to
you, you can't make them stay.Let them go. And it doesn't mean that they
are a bad person it just means that their part inthe story is over. And
you've got to know when people's part in your story is over so that you
don't keep trying to raise the dead.You've got to know when it's dead.
You've got to know when it's over. Let me tell you something. I've got the
gift of good-bye. It's the tenth spiritual gift, I believe in good-bye.
It's not that I'm hateful, it's that I'm faithful, and I know whatever God
means for me to have He'll give it to me. And if it takes too much sweat I
don't need it. Stop begging people to stay.Let them go!! If youare holding
> >on to something that doesn't belong to you and was never intended for your
life,then you need to......LET IT GO!!!

see your worth.....LET IT GO!!! If

thoughts of evil and revenge......LET IT GO!!!

Him......LET IT GO!!!If you are struggling with the healing of a broken
relationship...............LET IT GO!!! If you keep trying to help someone
who won't even try Corsiva''to help themselves......LET IT GO!!!If you're

particular situation that you are so used to handling yourself and God is
