If i was d, and a hospital was negligent to treat me do i have a case?

I woke up in the hospital. They thought i was just drunk so they put a blanket on me and told me to sleep ( i dont remember) when i woke up from my haze, i had scrub pants on and my white pants were hanging on a cheer next to me. They wer bloody. The ER umed i had my period. I had cuts, bruises and even a bite mark on me and they still thought i was just drunk. In my haze, i remember my ex runnin into the room. Shortly after i was wheeled to my car in a wheel chair. I barely remember that, to top it off i do not remember signing a release form, well discharge form. I peiced things together over the next couple days to find out that my ex was the one that did that to me. The hospital was negligent in treating me, never took a blood test for possible drugs such as GHB.. nor did they ask me how i was feeling or what i thought may have happened. In the end result, all possible dna, and evidence was lost due to employees not taking care of my needs. It litterally has thrown me through a whirl wind of hell. Its been a year and a half and its still hard. I suffer from depression and Post Traumatic Stress Disorder with flashbacks and panic attacks. Do i have a good case? Not to mention. My ex the one they released me into the care of, and the person that aulted me a few months after the incident is now in jail for murder. Nice.
