Linzi, I understand completely. I'm being treated for depression- have been since 4 months gone. I had a pretty severe case of post partum depression (thats what they call it in the US) after my first baby and my MW has been monitoring me closely during pregnancy this time. I'm on a very safe medication which makes all the difference in the world for me. Please feel free to PM me. I'd love to help any way I can.
