Hi and welcome to PC. Sometimes a person's body doesn't make the right amount of "happiness" chemical... and if an AD gives them a life, why would it be any different than a diabetic taking a medicine for life?

I hope you will begin taking your med soon, or call your doctor and discuss why you haven't begun it. Obviously you felt you needed it. Why not go ahead and begin to feel better, and enjoy your work?

Again, welcome.
