Oh, Iris - I am so sorry you've been suffering like this. I had PPD, too, but my symptoms were quite different. It still messed me up for a LONG time with the first two children when I didn't know what it was and I wasn't getting the help I needed. I was much better with the babies I had after those two because by then, I knew what it was and I was ready, had support systems in place.
I'm glad you're gradually improving and trust this will continue. Thankfully, we are amazing healing machines. Take good care of yourself, and thank you for sharing this story. It could help a lot of people who aren't aware of what's happening to them.
