Letting people "get to you"

I have recently discovered that when someone does or says something to me that hurts my feelings, or causes me to dwell on it for quite awhile thinking "why don't they like me", I found a solution, for myself. I took a notebook and began writing all my feelings and thoughts about the situation. I really let my hair down, so to speak. I said nothing badly towards the other person, just wrote about me. I also wrote that I forgave that person and that perhaps some of my human weaknesses were to blame...realizing that I am NOT perfect. When I was finished, I amazingly felt a LOT better and was able to "let go" of that, so that it does not bother me anymore.
