Im 50 yrs old. I recently was laid off from work but found new employment for which I always feel overwhelmed and unable to fullfill my job duties. That might be in my head because Ive been able to keep up with a lot of overtime and anxiety and nervousness.  I find myself crying uncontrolably in the early morning hours.  I am single and live alone so I can scream and crying until my hearts content. Im wondering if I have depression or symtoms of a heart attack.
