Oh, chick, no wonder you are angry I would be surprised if you weren't, after reading your story!
When you have the energy, I would like to see you write a letter of complaint to the hospital, and CC the letter to the Minister for Health (Nicola Roxon) and the state minister for health, too. It's a situation that has happened before and only recently are women starting to arc up about it and ask for proper treatment, where they don't a) get sent home to deal with it alone (or in a waiting room toilet cubicle) or b) get sent to the maternity ward surrounded by babies and birthing women. It's just dispicable - the big hospital bosses wouldn't be so happy to let these things slide if it had ever happened to them...
You're not alone here, unfortunately, though it means you can share your feelings with people who have had their own trauma and sadness
