An severe depression manifest itself in other way than just being severly sad, cryingl, no desire 2 try? i am not those, but have extreme anxiety!

Possibly: You may have an anxiety d/o which for some, can be as devistating as a mood d/o. You could also have a physical problem, like a thyroid condition. There are several different things which may explain your symptoms. My advice is to start by seeing a qualified physician who is best able to sort everything out. I wouldn't be surprised if your dr wants to order some tests.

endstage of anxiety: I often treat patients who present as depressed, but as a result of a long and extreme anxiety. Hence the old term 'nervous exhaustion'.
