Apparently, a "yes" answer to one or both of these is a pretty good indicator of depression. However, what about the person suffering from fatigue related to multiple sclerosis (MS)? I can tell you that when I am fatigued (around 11:00 am on muggy July mornings, for instance), I sure as heck have no interest in anything except feeling better - and, damn straight, I am sad about it. Sometimes this feeling lasts for days on end. Last summer it was months in a row without relief.
Is this depression? Is this fatigue? Is it a combination? I guess what is hard here is not just seeking a diagnosis, but determining how to treat the problem - I think depression should be treated by psychiatrists, plain and simple. However, how many of them specialize in MS and would have a general understanding of what the physiological effects of MS-related fatigue are? If you are unfamiliar with the fatigue induced by MS, it sounds rather unbelievable (and, frankly, falls right along the lines of many of the depression symptoms).
Anyway, the point of all of this is that while there are treatments for both fatigue and depression, treating either or both of these in the patient with MS takes some skill and patience to get right. Hang in there and don't give up. Remember, this is not your fault.
