How many times has your therapist seen you 'this' time? I too think she might be a bit quick on the meds. However, I was on antidepressants for pND after d6 was born. i think i was only on them for about 6mths(?). This year after all the crap that has gone on I had been going back to my old doc that I had when d was born. He was happy to put me on meds if I wanted them once he could see that I was in a depressed mood for more than two weeks and was having some trouble functioning. I resisted for quite some time till I was at a point where I couldn't think of anything else other than h adn my sitch and felt that I needed some help to raise me up to a level where I could start to deal with things objectively rather than emotionally. IF you feel so low that you can't pull yourself out of a funk for longer than a day, then consider taking antideps for a little while. I don't think most of them are addictive and it doesn't mean you'll have to be on them for life. for a lot of us, depression is a response to a situation rather than a chemical imbalance and it may help you to have a chemical kickstart to get you up to the next level of self help.
Hope I've made sense...I have a bad habit of rabbiting on....
