What happens to people who are only children who grow up with a single parent and no friends?

I just thought about this because that’s exactly what I am. I have a single mother who plans on never getting married, most immediate family is 16 hours away and I have a long-term relationship that’s my sort of my entire support system. Even my partner has a bigger support system than me like multiple friends siblings but not really close with his parents. I think about that a lot if you don’t have a support system that you can reach out to most of the time because of work and distance what do you do?
