Mental illness

Mental illness is an empty label. You cannot say someone is absolutely crazy. They are only relatively crazy. Though the label often fits very well, and describes someone quite accurately, it's still an empty label. What is the significance of this? It means that someone really can say, "I have bipolar" or "I have schizophrenia" without being in bad faith, while they can also feel beyond that label because the label is totally illusory.
