Pregnancy hormones are a bit of an odd ball anyway, impossible to predict in advance how they will affect a person. I'm not convinced that other emotional issues are overly related to ones related to motherhood either. There are obviously many issues there - some related, some not so related.

I usually end up talking to someone though - now, I have a husband who has also struggled, so it helps. The usual people aren't particularly helpful though - I've generally had to be my own doctor on so many things...

Anyway, you know where my Discord is. :-)
Chat whenever.
