Interestingly enough, in the United States, people tend to view depression as a sign of personal weakness; in which case, I would like to pose a question about how they would view someone that suffers from bipolar disorder manic depression.
I mean, you can see the depression when it's there, and you can also see the mania when it comes about. Ask yourself that question, "is this person, a sufferer, a weak-minded person, or just the victim of circumstance - a victim of a disease?"
Be under no illusions about the reality of the situation, bipolar disorder with or without manic depression, is a disease. It is a serious disease of the mind, and nothing else. And like all diseases, there is a cause and a cure, even though we do not know what that cure really is at this time.
And about the cause, we can only tell at this time that it is related to regular depression, and the genes that the sufferer inherited from his or her parents. This is one fact you need to bear in mind about this mental condition that is plaguing many people today.
Psychiatrists and psychologists acknowledge bipolar disorder as a genuine malady of the mind, albeit caused by various factors, which plague regular humans. In this view, you need to understand that the best way to go about dealing with it is to get one of these professionals to help out. At least after a couple of sessions you may find out about the perfect medication for it. This is better than assuming or believing just what any person says.
