I have had post partum depression 4 times... I tried St. John's Wort and it didn't help me. I take a multi vitamin anyway... that didn't help me. I tried exercise, I didn't see much of an improvement...
I didn't want to be 'dependent' on medication and there was a big stigma with admitting depression and being on medication (my father and my husband both believe that pharmaceuticals in general are some form of government control - seriously paranoid bunch of guys)... i got over it when Paxil worked... my husband hates that I take a little yellow happy pill, but he's seen me without it and agrees that I need it :)
I really tried to fight the whole idea that I had post partum depression... I just thought life sucked with kids and that's how it was.. life was tough and suck it up, right?
post partum depression can escalate if left untreated. If your counselor is suggesting you take medication then it is probably the best course of action for you. I have only needed the help of a medication for about 6 months and then I go off (though don't do this abruptly - it's a long two weeks.. and it's not safe - i had to do this with my 2nd because i lost my health insurance and i couldn't afford my prescription, and my doctor would not give me samples to help me ride thru the storm and do it slowly, in hindsight I realize the risk he took doing this... but i survived the ordeal).
Good luck with whatever you choose... my depression was severe and truly needed the help of pharmeceuticals...
my only warning... be careful what herbs/natural things you put in your body... 'natural' doesn't mean it is free from side effects,... some of them cannot be taken together, and they vary widely in concentration and quality. So do your research... maybe contact a homeopathic doctor who can monitor your progress and give you dosage information and recommend good quality products.
Good luck to you! feel better :)
