I also have been and continue to need to be on zoloft. I'm not saying that you are like I was, but frankly I was a complete mess for a couple years, at least after my loss. I was depressed somewhat before my loss, so I think what was a problem for me, became a hundred times moreso after losing kai. I don't think I'm abnormal or anything though, it is a rare person that doesn't dip into despair over this.
I'm not sure what meds you couldn't take, I guess the ones for bipolar disorder they want people to get off of when pregnant? which sounds very difficult. Don't be afraid to go get some help.
