50 year history of depression. Suicidal thoughts. Had nervous breakdown in April 2012 when I lost my job of 22 years. That is why I have no energy, no will to live. Short of breath at times. Pain in arms and numbness in hands from 3 and 4cervical vertebrae deterioration. Sleep til noon; no will to get up. Some days I just stay in bed. Could this also be alzheimers setting on?
