Hi there. I've dealt with depression and anxiety on and off for the past five years. Generally, my depression and anxiety are reactive--- basically, if my circumstances are bad, my brain overreacts. But now, it doesn't feel reactive. My situation isn't great, but I feel like I can't be alone or idle for too long without falling into a state of depression (low energy, feeling of pointlessness).

My question is, have you ever experienced depression as a part of another condition? Or do you know of depression being a "symptom" of a bigger health issue?
