I just need to share my feelings as worried I'm on the road to PND 
Brief background - struggled with eating disorder most of my life. Lots of bereavement last year led to 3 months signed off work earlier this year for depression. Didn't take meds throughout pregnancy and towards late pregnancy started to feel I didn't need it. I'd only taken the anti Ds for a month back in Jan when I found out I was pregnant. Did not enjoy pregnancy (body changes, pregnancy rage...). In a much better place in terms of being free from physical eating disorder symptoms lately, but I'd be lying if I said I managed to be clear of it completely during pregnancy.
Fast forward to the issue I'm facing now. Baby girl arrived at 34+6 after waters broke the night before (she arrived just 8 hours after waters breaking). Very quick, pain-relief free labour and she's absolutely gorgeous (and I'm so happy I got the girl I was wishing for!). I'd not had time to have second steroid injection for her lungs after going into labour, so when she was born she had to have a cannula in for antibiotics (2 days) and we were in hospital for 3 nights in total as she needed phototherapy for jaundice.
Week one I felt very primal, on a high, just so full of what I can only call 'beyond love' for this perfect little thing. Second week hasn't gone so well for me mentally. I keep reading posts about preemies and am hating myself and blaming myself for it (mainly, I think what caused it must have been my eating disorder). I feel so intensely sad that she may have long term problems as a result of being 5 weeks early and can't seem to shake myself out of it. DH doesn't blame me at all and keeps saying look at this amazing little girl you have grown, and reminds me she's a great feeder, was 5.6 at birth and is putting on weight and all midwife/HV have said she's doing well and don't seem concerned at all, but I still hate myself because feel I can point to a wholly shitty reason for her early arrival.
I'm not keen on starting meds for depression (am exclusively BF) but equally don't want to make my little girl's life worse by having an anxious mum.
Just looking for a bit of support I guess xx
