I believe that I have been depressed since junior high school - about the time when menarche appeared. It took a perceptive MD to see the symptoms and suggest some counseling and antidepressants when I was in my 30's. Since then, I took them for a year, I went off for about 5 years, and then went back on when I moved back into the Midwest. I don't think I'll ever go off them again. "So this is what normal people feel like," I say.
The only reason it seems that more nurses are on them is that we are aware they are there and see how they help many. If everyone could see that, there would be even more people on them. Kind of like insulin pumps. Did you know that a high percentage of the people who are on insulin pumps are healthcare-employed? Knowledge changes the game.
