World of fantasy

I'm gonna let go of what's not mine, I'm not sure if it's hurts , I'm not sure if it's painful ..what worse could have happen , trying to find my way out and will it make me sad ,I'm not sure atleast the pain will be less than before, will it leave the scar , maybe or maybe not. Have you ever seen a person getting hurt by words and the scar appears. By letting go will I be able to start a new life.. only time will tell. Will I be happy if I let go likewise I'm not sure. Some say letting go will bring change to oneself, some say it will become worse if we keep holding tight. The things I've lost will it come back if I let it go. But why do i look back if I'm letting go. Trying hard not to remember but I can't erase it, will those things I had in the past haunt me, again not sure but by trying to let go will I only know if it's true or not. Will the world change if I let go. Again some say it will , some say it won't . Why does it hurt
