I was feeling really down in my first week or so, DH was worried about PND, and so was I a little... I found this questionnaire online & did it, I got 16 out of 30... I figured that was just over 50% so completely normal, plus once I got all the guilt out about breastfeeding not working I felt a million times better... Link to questionnaire below;
I think the more you talk about how you are feeling the better off you'll be & if you can't talk to your DP talk to us or another Mum that will understand what you're going through.
if you are still feeling the same a few weeks in definitely see your GP your mental health is too important to risk XXX
