A lot of people say they "create" their own family or earth family how do you do that?

When I was younger and dealing with my dysfunctional parents, I came upon the idea that we can create our own family here on earth. Or we can choose our friends, unlike our family. I know a lot of you are married and so will say that is your family. But finally all my family are now deceased. I spent a lot of my time and energy, ten years to be exact, on taking care of my ailing parents. I have other issues too, so I isolated myself. It may be a question with no answers but how do you start to create a new family. I really do not want to be all alone on this earth. It never really worried me before but it is now.
