Hi Matt,
I thought I’d share something that may help you because it’s helped me. For so long, I held in so much pain and resentment towards others who had wronged me. Their actions had complete control over my emotions. A first step that I suggest is to actually experience those feelings you have- actual emotions (i.e. sadness,anger) rather than intellectual interpretations of emotions (i.e. jealousy, self-doubt, self-worth). Sometimes we come up with stories in an attempt to justify or explain how we are feeling. Another suggestion I have to to acknowledge them as someone who made a mistake and acted from what they knew at the time. Simply that. No more, no less. It’s helped me to remove my own biases towards that other person and acknowledge them as a human being. You will get authentic power from that. I know it hurts and you have the right to hurt. But, the more you can actually experience the pain, the easier it will be to move on and feel better about yourself. That’s just a start. All the best, my friend.
