Everyone has some sort of problem, so I suppose "okay" means that you do not hurt other people on purpose, and that you can have decent relationships with other people.
I have questioned several times in my life, "Did I turn out OK?" Then I think that I have managed to stay married for almost 20 years and have a great relationship and I think, OK, I can at least have a good relationship with the person I live with, so that must mean that I have some good emotional/relational stability. Then I start to question it - maybe he is just a really together guy who can handle me, when no one else can. Or maybe there is something wrong with both of us, but it works somehow, so it appears to be normal. Ah, too much time spent in the brain!
I just pray that I don't mess up my kids. I see my other friends do these foolish things to their children while they remain completely oblivious to what they have done. And I start to worry that I am messing up my children somehow, but don't know that I am doing it. How many people pray, "Lord, don't let me mess up my kids." I bet it's a lot.
It would be nice to define ok by my own standards and not have to worry about other people's standards, but as an INFJ, I have a feeling that will never quite happen successfully.
