You will never truly understand the struggles of another person. Remember to realize how hard your own struggles are for you. The other guy feels the same way. We are all trying to make our way in this world so make it easy on everyone and don't judge.
This is now one of my favorite thoughts ( besides that I fall so much) but we do lose ourselves or our balance and once we hit bottom… look around and look up…. you have no further down to go….I know this as a personal life lesson… and it taught me.
