Instead, you need to be MORE judgmental. You need to reject your situation EVEN HARDER. Definitely DO NOT move to a huge city (unless you have people there).
Your problem is that, up until now, you have been following money and interests, and expecting that the belonging issue to sort itself out.
This is a foundational mistake, it's completely backwards. You need to belong FIRST. Your interests should stem from the needs of the people that you love, your tribe. Your work/employment should stem from the needs of those people, and your role in what they are working towards. The other way around does not work.
Basically, you are alone because you were misled into prioritizing the wrong things. Turning that around will involve a lot of pain and sacrifice.
Find the people that you actually love, love being around, and love being connected to. Find them online. Find them through extended family. Find them through old friends. Go travel, and reconnect with your own people.
These people exist! There is no reason to settle for less. Stop what you are doing now, and orient your whole life around this. Once you find it, go find more people like yourself and pull them into the group. So many people like you are trapped in this same situation, and they need your help.
