In my experience, unless people can REALLY see the change and see it NOW, they grow impatient. That is, these changes tend to happen gradually. We don't wake up one day and feel fine. Its difficult to show these changes when someone only sees us every so often. Even when you tell them its not about them, it doesn't seem to make much of a difference. I think that people can be quite selfish in this way. I mean if you were suffering from a physical injury, you'd get as much time as you needed to heal. But when its mental, the "snap out of it" attitude seems to prevail.
