I don't have a good answer. Sometimes I don't even know if I'm ok. Or I think sometimes I think I'm ok when I'm really not. Mostly I just walk around trying to tell myself I'm ok. Yeah, I don't know what people mean by it. What is classified as 'ok'? I, too, would like an answer.
I don't think I've ever said I'm not ok, but people have looked at me and said I'm not. I think in the back of my mind, I classify being ok with how suicidal I am. Probably not a good approach.
