The reason most likely that you would not see much of this topic posted is that it is easy to say so and so did this to me and that is the reason for my hurt and pain, rather than saying I need to take a deep look at myself and find where my anger is coming from and remove it.
I had a friend who suggested to me that I take a candle into the bathroom and turn out the lights and talk to myself in the mirror like I would a friend and council myself. The purpose of this is 1. your features would seem much different adding to the ilusion that you are talkin to someone else and 2. I have found this even for myself that we give others very good advice but dont save it for ourselfs.
Once we have found the source of our anger it is prudent to forgive, I found myself everytime that a memory would come up to the surffice that was hurtful I would simply repeat over and over I forgive, I forgive. I found by saying that I could let go of hurt, pain and loss, the very things that cause anger most often.
