I don't know how old you are but with experience, you will come to realise that MOST people are struggling with very difficult situations and, you are going to have them more and more as time goes on - inevitably. That is the human condition.
You lose girl/boy friends, best mates, parents, children in more or less horrendous situations and unexpectedly. Ditto jobs, houses, hopes, career prospects. Don't be fooled by people who appear to have a wonderful life - it may well only be what we, in our ignorance, perceive and they are very good at covering up. They have learned not to frighten the horses ( or other people.)
That is why I said it isn't the rewards, success, money etc that will give you satisfaction ( 'sic transit gloria' ) but the ability to help others and do something however small to help us all to get along the best we can. Courage and kindness is what we all needed.
