Dr. Beth,   I have been running on empty for quite a while. I don’t feel motivated at my job and I have no drive to take care of things at home, but I force myself to do some of them anyway.  I feel like I have less patience than normal and tend to get angry easily.  Basically it seems like life is no longer “in color”; it is just plain gray.  My wife and a female friend have recently suggested that I may be suffering from depression, but I don’t know if they are right. I don’t cry easily or overeat or oversleep like my wife does when she is depressed. Do you think I might have depression?
