Let me give this a try. Do you have a history of depression? Why are you on your meds in the first place? There must be a reason. Is this the first time you have doubted your diagnosis? In the past was your depression without meds getting in the way of you functioning day to day? Have the meds worked for you in the past? What happened in the past when you attempted to get off your meds?

This is all that I can think of. I suppose clinical depression can come and go for some.
