Creating new meaningful professional relationships has become hard. I'm a member of a few online communities, but they're more centered around specific questions and answers. I'm happy to chat and share my knowledge, but it has never translated to some kind of connection.
How do you deal with this issue?
You know, the majority of people lived with a small sphere of friends since grade school. Your typical junior high kid doesn’t have that many friends, and they cope with it and many cope with that for almost 20+ years.
Were you a popular kid in high school? You’ll just have to learn coping mechanisms if things have changed, but many many people deal with a small sphere of connections just fine since childhood (and some literally deal with none).
If the kids can do it, you can do it.
Volunteer. If you are a dev, reach out to local bootcamps and see how you can help. In my experience, they would love to have an experienced developer zoom in and talk, or mentor.
Online communities around slack/discord are more real time and may make you feel more connected than async ones like HN.
