Nonnie.............Clinical depression used to be known as Endogenous depression. It is the deletion of certain chemicals in the brain, so there is no obvious cause, unlike reactive depression (which is caused by bereavement, divorce, the usual stresses we all experience at times). ANY type of depression is horrible, but the Endogenous one (I have had that on and off for 30 years) makes a person feel very much a fraud, a failure because on the surface, life can be good. I've got a lovely husband, my rock. My AC are great, we all live within 1/2 a mile of each other and get on very well. I only work P/T, in a job I enjoy. My mortgage is paid, I haven't got any debt. I've got friends, hobbies, live in a quiet, decent area.....but at times I wish I could go to sleep and never wake up. Ridiculous, when I think of people who have actual problems. There we have it...
