Troubled Heart

My heart is troubled. I have a conflict with someone and I'm not sure why! Can't figure out what happend but something most definitely did. So after much prayer I went to this person and asked what I had done to cause problems. Was told that I didn't do anything. But I know this is not true...because it has been spoken to another person. And I guess it just troubles my heart that someone can have issues with you, have an opportunity to talk to you about them, and choose to tell you an untruth and then speak about it to someone else. I sure wish I knew what to do or how to make things right. My heart hurts tonight. Well, my heart has been hurting very deeply for a week now. I guess I just need to trust God to heal my heart and pray that God would deliver me from the current situation.
