I recently had a disagreement with someone at my child's school. I've reached out and been conciliatory but they haven't really responded or met me halfway. I know I just need to let it go, because I've done all I can to try and rectify it but I can't seem to stop thinking about it. I replay the interactions over and over in my mind to the point where I can't concentrate on other things. I need to move past this but I can't.
