"Resentment is like drinking poison and waiting for the other person to die."
Forgiveness isn't always an easy. I still catch myself hating others or even myself but it doesn't get me anywhere. So I stop and think. I ask my self why is it so important for me to dwell on something that has already happened. I wasn't happy about it then so why would I keep bringing myself back to that moment. The past is the past. I have to learn to leave it there. I have to break that cycle. Thinking about forgiving yourself or anyone else isn't going to make you feel better unless you just do it. I tell myself that I have to make a choice , either I'm going to forgive and be happy or carry that resentment on my shoulders and continue to make myself angry and upset. It's been working for me.
Break the cycle
