Hugs from an internet stranger!

Our communities are setup like that. We're separated from eachother, and we can't afford to spend enough time at local third places to feel community. Church also used to be central to community and most people aren't religious, but nothing has replaced the churches role in community building.

It's rough. If you can get out to places nearby where people congregate that will be nice. Getting a dog is nice too if you like dogs, they give you love and accept your love and they're a good ice breaker. They also force you out regularly. You can take the dog to dog parks and chat with locals.

It's not your fault. Humans are a social animal and we built cities and an economy that didn't consider that.

It is important that you love yourself. In fact, I think it's important that you feel loved by someone, even if that somebody is yourself.
