I missed the boat on that too. I'm your age but I know that it's possible to meet people, it just takes some real effort.

I made a new friend at a hackathon recently. Since you're here on hacker news you could try attending events such as programming meetups, hackathons, tech workshops, conventions etc. It's easier to bond when there are mutual interests.

Otherwise try joining some sports related club, e.g. a local gymnastics or football club or even just a jogging group.

It is different but there are people who want to hang out, even if in the context of doing some other activity.
