What exactly is "attention seeking"?

This has me curious

Is going to a therapist because we want attention from the therapist? I would hope we go to a therapist to work on our issues, but sometimes they also give us positive attention (at least I would hope they do)

If we are fortunate enough to have any family, I would hope they give us positive encouragement rather than negativity and blame although sadly this clearly isn't always the case

And what about posting here?

I know that I post for support and feedback..

Does anyone ever post just for "attention"?

I don't think I've known such a person
