He's 19yo, a real introvert and struggling with life since his father's death. Doesn't seem to have any friends.
I'm really worried that if anything happens to me, he'll be one of those people who has no one to turn to when times are hard and end up on a park bench. I have often thought, the difference between me and people who are really down and out is only the support network I have. I've never had to use it, but knowing your parents wouldn't see you destitute does give a lot of security.
My Dad, who has been very close to my boys has cancer (and is 79) and other than him there's only DS1, who is busy with his own life and although they were very close in childhood, have very little to do with each other now.
What can I do to protect/prepare DS2?
Financially there'll be some money, but none of the practical support that comes with family.
