I stopped taking my anti-depressants

When my son was only 2 weeks old, I was in the middle of a severe case of "the baby blues"  My husband swore I had PPD because prior to going into labor, he had JUST gotten home from a 2.5 week hospital stay from his incredibly debilitating accident at work.  I was 8.5 months pregnant when this happened, and only 2 days after he came hom I went into labor.  So here I am with a newborn to take care of as well as a husband I had to help shower, dress, & eat.  Not to mention trying to help him with the depression he was going through.   My Dr said I had no chance of not getting PPD, but i just don't think I have it.  She prescribed me anti-deprressants, and a few nights sleep.  After 4 nights, I felt GREAT!!!  I stopped taking the pills that week.  My son is 7 weeks old now, and I still feel much better.  Not to mention my husband is getting better as well, and can finally help with his son.  Did I jump the gun going on them?  Or off them??  I just don't think they were necessary, and because I was so sad I felt at the time I would do anything to help me feel better.
