It is all dependent on how the patient feels. If they believe their symptoms have disrupted their lives than they are in need of help. People who are easily stressed out, and have poor coping skills, and who are chronically disrupted by the consequences of their choices are signs of a psychologically un-healthy person. People who are healthy have an internal locus of control, have good coping skills despite events, and who are not chronically disrupted by events or consequences of their choices. Psychologist know who is un-healthy and who are. It is very clear. I listed them above and these characteristics are in the research material. It is possible to become healthy after chronic issues in the past.<br />
BTW it is not normal to have such high highs and such low lows as in bipolar disorder. And the proof is in how much the "bipolar" person suffers relating to the consequences of their actions. For instance, high highs and low lows affect how other people relate to them and so chronic relationship issues might take place. This could be a sore point for the sufferer. There are physical, chemical abnormalities related to mental illness. This is why bipolar sufferers must be treated with medicine. Some bipolar people do not recognize the depth of their disorder but the people who grew up with them and who love them know all too well. This means there is insight deficit. Sometimes we must listen to our loved ones when they try to give us insight into how our behaviors affect them.
Here's another slant on this whole question: Years ago I went to a shrink for alcoholism. At first I knew him to be a sincere, caring, married man of about 42 with kids. He wore a suit (no tie) and had a lot of books on his shelf about substance abuse. By the time 3 years had passed he was turning up for our sessions in shorts and sandals with a good tan and was alluding to affairs with young men in Costa Rica. His eyes were red most of the time and he seemed to be having trouble concentrating. I had stopped drinking. About a year later, after I had moved to another town, I learned that he died of a heart attack. Yeah, sure. <br />
We can theorize and philosophize about the human condition but no one can ever really know what is going on in another person's mind.
No - we all think differently, so there's no Standard to go by. Without a standard, you cannot declare anything. So, the crazies win *party*
