I'm home with no plans. Just our little family again going alone to one place (outdoors). It feels so lonely. Everyone else in NYC is out and about with friends or am I just feeling sorry for myself? Normally have so much going on and it feels weird. We just returned from the city after being gone since March. I'm having a hard time adjusting. Yesterday walked around the Village and it just felt so off. Not dangerous and yes people were eating out but it just felt like such a repressed vibe. Am I overthinking this?

We are coming back soon. Before the pandemic I felt really lonely. Then I felt even lonelier. And now - I kind of enjoy being alone, if that make sense. so many friends have gone gonzo nasty during this - unable to cope - and I would rather just step back and be with me and my family. I don't feel ready for full closeness again with any but one or 2 friends I've stayed in contact with.
I feel like we all have to make a much greater effort if we want to be social right now. A Lot of people are still away, or not socializing, or quarantining
To the OP - yep, if you've been gone since March, then you definitely will need to readjust to the city. But we've all been here, so the current mode here doesn't feel repressed at all. Plus, many of us have specific friends that we are comfortable socializing with - outside, so we have plans. Were you socializing safely when you were in the hamptons or catskills or wherever?
My neighborhood in Brooklyn is a big outdoor party. The street on our corner is closed for outdoor dining, there are live bands playing, people have brought out their own little tables and chairs with candles, the restaurants have strung fairy lights, children and dogs are running around. It's downright festive.
