text: The short answer is that yes, it could be a sign of depression, but only if combined with several other factors.  I would advise you to go to the doctor and get checked out for physical problems - then if none are found, you should probably go to a psychiatrist for a consultation.  In addition, a full battery of psychological testing would be a good idea, if possible.  Check out the link below for the signs of depression - you have to have 4 or 5 most of the time, for at least 2 weeks, without a situational cause.
