I was just about to ask something similar to this. Whenever I'm depressed, usually I'm high-functioning but very teary and self-destructive. The symptoms were all mental, not physical at all.

Just recently I've started to experience the physical symptoms of depression, such as hypersomnia, muscle-stiffness, and flu-like aches. Last episode I spent two full days in bed, either sleeping or crying. Now I'm experiencing many physical symptoms of depression (headaches, stiffness, sleepiness) but very few mental symptoms. Is that normal?
