Not having people who share my worldview is what makes me feel lonely.

And that's incredibly arrogant, I know. "Oh, so people have to agree with you, is that it?" Yeah, something like that, but spontaneously.

Most people feel lonely when they don't have other people to do things with. I feel a very minimal need to share experiences. I feel a need for presence and attention, but mainly a need to have people who share my view of the things.

"Am I the only one who thinks this way?" is the question that makes me feel alone. People loving me don't quite fill the void of loneliness. I feel the need for people like me, for equals and equals in thinking.

I was accused of this many years ago by a guy and it's true. I disassociate myself from people with very different ideas not because I despise them, just because I don't feel a connection. I always thought it was Fi, but maybe it has a bit of Ti in it? No idea.
