I have to agree that the anger can be part of depression. I have a family member that is angry all the time and lashes out at everyone, for everything. (Getting worse as his depresson has gotten worse.) There is new research that points to anger attacks actually moderating the depression for the depressed so it lessens depressive symptoms. I believe that for my family member, the angry outburst has become the 'drug' to lessen the depression, it happens that often and for no reason. It has something to do with homocysteine serum levels in the brain. About a third of depressed people are prone to anger attacks. If the depression is treated, many have a decrease in anger as well. Good luck!
