I would go further and write the head of the facility about your experience. I would, however, leave out the PTSD and depression, and just stick to the experience and the horrible treatment you got afterwards. if they read that you have difficulty coping, they will for sure tune out the rest of the complaint...

Whether or not they will reply, you will feel empowered in just writing and letting the heads of what shoddy treatment you received...

Now I hope you can shift your perspective about what occurred and be proud of how you stuck up for yourself!! That was awesome, and I don't think I would have the gonads to do what you did!!
