Well, you are not alone. I am also a mom who took an antidepressant from 3 wks postpartum and then had depression (and psychosis) issues later. During my first pregnancy, I first noticed heightened depression at 5 or 6 months postpartum (without meds), and then during the second the same thing happened, even though I was taking Prozac. In my case, I had a complete psychotic break and had to be hospitalized after the 2nd baby quit nursing at 11 mos. I know that this is very rare. What I would recommend to you, however, is that you see a psychiatrist if you can, to regulate your antidepressant rather than just your OBGYN. You might need a higher dose. I certainly wish I had done so much earlier than I did. In any case, see a doctor. And hang in there.
