Hi,
I don't look at Mumsnet very often - tut tut you say!
I check in occassionally to see if anyone is struggling with Pueperal psychosis (severe PND) as I suffered from this in 2003, really just to give a bit of hope.
Both Peuperal psychosis and PND are totally treatable and temporary and you do get over it - FULLY. I'm living testament, I have a great daughter who was totally worth the hell, a happy marriage and hold down a full time job - I'm totally back to the person I was and more! I recovered and so will you / yours.
Get some treatment, accept all offers of help and give it a bit of time (in my case vast improvement after 3 weeks gradual recover over 3 months)- it's all worth it in the end
Love to you if you are suffering, remember it's TEMPORARY.
