How do I learn to let go of the past
I had originally a great life I was very happy and enjoyed life but then something happened and it all the sudden went from great to cool to ok to bad to barely acceptable. I am holding on to everything from my past and can't draw the line anywhere. the memories of the past are so good they feel like torture now because of how bad life is now and how great it was back then. how do I learn to let it go?
