I had a very similar experience to yours, only mine happened at home. I've contacted everyone I can think to contact and I've been through a year of therapy, and all I can tell you is you are right to be angry. The medical and legal systems are both letting women like us down, and there are a LOT of women out there who are just like us. What these medical professionals are doing is wrong; it is violent, it is dehumanizing and horrific. It changes you in ways that people who haven't had this experience can't understand. Some people find the term "birth rape" offensive, but I found it very comforting to have a word that was shocking enough to truly express what happened to me. It has helped me process the traumatic event and understand what has happened to me emotionally and psychologically since.
There is an online support group at http://www.birthtraumaassociation.org.uk/
that I've found helpful at certain points. You may want to check it out, but I'll warn you that the birth stories on this support group are not happy miracle stories and they may trigger emotions and memories that you're not prepared to deal with yet. I've found the stories very helpful myself, but I'd give it some thought before clicking.
I fully support your choice to not share your entire birth story until you are ready. We are on a healing journey, and it doesn't happen over night. Don't rush yourself to read other birth stories, either, unless you feel ready. If you find yourself up at night processing things, though, and just want someone to talk to, I'm here. I'll gladly listen, share my own story or whatever it is that you need at the point you're at.
Peace to you and yours.
