I've been struggling with my feelings since the birth of DS last year; I haven't really bonded with him at all and even though he's an 'easy' and happy baby, I often wished he would disappear 
Anyway after reading a support thread on MN this morning I finally admitted to myself and DH that something's not right.
I haven't yet been to the doc although I did go 18 months ago when suffering badly from sleep deprivation with DC1, so there is some vague history there.
DH was totally a little shocked by my breakdown and hysterical blubbering; he did try to make me feel better and refute my claims of crapness, when all I really wanted was for him to listen and try to understand. I'm glad I told him though.
I'm interested to know who other people told of their PND, and what kind of difference it made. I'm wondering whether to speak to my DMum, she probably suspects anyway
but not sure what it would achieve, IYKWIM.
Sorry this is a bit waffly
