Thing is - there are ssri drugs that seem to be very safe in pregnancy.
I have had two friends suffer with pn psychosis- I suffered from severe, acute pnd and ocd. It bordered on worse at times. It was a very specific feeling and it was undoubtedly physical in origin. When ds didn’t sleep for 18m I was a mess too but it was a very different struggle.
The female unique nature of ante and post natal depression, psychosis, anxiety and ocd HAS to be kept separate because it is a separate, female physiology specific etiology
I am all for depression being recognised and treated better in men - it needs a different label and approach though. It is effectively an adjustment disorder and women can suffer that bit as well. It’s not the same as pnd/pnp/ocd/anxiety
