depression
"I've always had anxiety more than most for years since I was a kid. In last few years (I am 50 yr. old male) this grew into depression. It got to the point I would get paralyzed on the next task over thinking it - I couldn't be decisive. Then I would get depressed because I couldn't get things under control which led to lack of sleep - continuous cycle. I was always against anti-depressants (for the weak I thought). I tried everything - exercise, no alcohol, no sugar, sleep aids - with little success.  I finally gave Lexapro a chance.  It brought the anxiety noise level & depression way down and allowed me to get perspective and sleep. Occasional chills, but less over time. No other side effects for me. Glad I did it."
