As the last person in the family, I feel I have let them down in some ways, like not having anyone to carry on the family name after I'm gone. Not to have anyone that will recall the adventures and stories and experiences. Some people think its overrated. But..
I try to cheer myself up by saying I would probably be a terrible parent. But....
It can be hard missing out on something that others take for granted. But it's never too late..
Believe me when I say that I know what you mean. I wouldn't try to convince yourself that you would be a bad parent because I know better.
