Hi Bec,
Firstly welcome to BB. I am glad that you found this site, there is alot of support on here and has been a font of information for myself, DH and our bubba.
I am sorry though that you had to have such a scary time after your DS's birth. On one level i can relate as my DD stopped breathing a few hours after birth and was on oxygen overnight and had to stay in SCN for almost 72 hours. the experience also left me a bit anxious. and i wouldn't be surprised if it contributed to my experience of PND.
There are a couple of things that i recommend:
first, when you write to the hospital, dont have any fear of adding the emotion! i used to work for the director of surgical services in one of the leading hospitals, and trust me, those letters we get are really important for getting things investigated. the thing to remember is that the hospital will ALWAYS find themselves at no fault. so it is wise to keep your strenght when you get the (i hate to say it, but most likely will be) the invariable letter stating 'that after a thorough investigation....the hospital believes it acted within safe blah blah blah. this is their first line of defense (kind of to sift out the easy targets). if you would like to see more answers, then reply and also, if you are up to it, call them. I know that it certainly got things moving at where we worked.
second, like Trillian said, i can recommend finding a good support network in the coming weeks. I waited a looong time before getting support and a good ear to chew about my experience and i can only say that i wish i had found BB earlier!!
through BB i have found awesome girls (and guys!) that have provided me with rock solid support and not to mention hearty laughter! through here i have also found a great 'real life' support group for girls with PND. i can't rate each and everyone of them high enough.
take care and I wish you the best! have you found a 'baby buddies' group on here yet? (under the baby and toddler section). they go by month and year of your bub's birth. the girls in my group have been my rock!
