If your medications are not working, then it's time to switch to something else! Many times, an antidepressant will stop working! We become "accustomed" to a particular med, and we have to switch to a different one. That happened to me -- I was on Prozac for quite a long time, and it didn't work anymore. So my doc switched me to Cymbalta,and low and behold I began feeling MUCH better!!!
It was great --- no more terrible lows. So talk with your doctor about your meds! I'm sure he can help you!
I agree with Lee. My pdoc had me on Paxil at one point. For a year I felt like I was walking around in a depressive fog. I kept asking him to discontinue this med but he kept putting me off. Finally in desperation, I stopped on my own (I know BAD, BAD!!!) But what a difference! My mood improved, I was able to focus in school and the depression disappeared. Even he had to admit that I did the right thing, and you'd have to know my pdoc and his ego to realize for him that was huge!!
So definitely talk to your pdoc about your meds - good luck
