we've been through some traumatic times in our life with ourselves and the children and no matter how you are suffering and the grief/disappointment/life not treating you fairly etc... you go through, you then always see (on tv or otherwise) or in our case the childrens ward where our son was, that there are other people who are going through a tougher time then yourselves & it puts your life & situation into prospective.
Thank god there are still some kind hearted folk out there that'll stop and help & give some of their time and help those who are in need.
I'm a great believer in things happen for a reason.
