You can't always trust your emotions. You can't always trust your feelings. And I'm not talking about pain but I'm talking about more about life issues where something happens to you or somebody says something to you or somebody said nothing to you and you're waiting for them to say something to you.
If we all could be a true friend to someone, praying and encouraging one person somehow, that's a first step in being part of making the world a better place.
Yet I also believe that when you do unto others, blessings come to you as well. So if you don't have a friend, be a friend. If you are having a bad day, make someone else's day. If your feelings are hurt, heal those of another.
