Mental Health Support

Both my parents were only children. Wife only had one aunt. So we have a sparse family. We're in a big city so we see extended family once in a while. But I'm facing that as we only have one kid.
I can only suggest looking for a group of some sort. My mom and a neighbor did red hat ladies, not MAGA predates the pumpkin. Call a local newspaper and see when they publish groups and events. Libraries often have listing and on site events and groups. https://www.meetup.com/ is another.
Best wishes I'm sad how our nation can really make lonlyness feel extra accute.
