I am so srry fr your loss. I don't think it is called post natal depression but the chemical changes in your brain would definitely be similar and with all the other circumstances it definitely sounds like clinical depression. There are other options out there if you don't want to go the medication route. Talking to a councellor, meditation, writing your thoughts down ( keeping a journal), certain naturopathic remedies and many other ways you can probably find out about searching on the web or talk to your local womans health clinic. Good luck and remember people to care.
