haunting temptations of the tongue

It keeps coming up again this thing that I can't deal with without help. I feel like I need to say something, to rant and rave and get through what I'm feeling exactly and let the person know how hurt I was but I just can't. My tongue gets me in trouble when I let it say exactly what I want it to. I just can't let my words inflict hurt on another because I know that they have that kind of power. The temptation to say the things I want to say is so strong but I think it is wise to hold my tongue.
