Crying has nothing to do with being strong. Strong people cry too.
It's okay to cry for those who are sadly lost in addiction, it's okay to cry for ourselves. Crying is natural and helps get out emotions out.
But it's good to have a good cry and then do something good for ourselves. We don't need to slip into a depressed sad state, we can just express our sadness and then find joy in life because it's out there for us to find.
