I disagree. I used to look back at my past and be embarrassed, angry at wasted time/potential, and all around blame for where my life is now. Now I look back with compassion, past me was going thru some rough times with basically zero coping skills and an inability to ask for help. She was doing the best she could with what she had. This shift came about for me when I stopped worrying about blame and started to accept what had happened and immediately look for solutions. When I accepted the past is the past and cannot be changed no matter how many times you relive it inside your head.
