I don't know how to get legal justice here in CO when I was assaulted at a rehab facility in FL in January reported to CEO and the did not file report

I was assaulted by two men on site at a substance abuse rehab residence in FL. I sustained injury and re-occured extreme PTSD - both being treated for now. I reported in writing and verbally, demanding investigation and police reporting. Neither happened, although about a dozen or more staff knew of the incident and several other residents. since I was not allowed to use a phone without approval, I could not call for myself. After I demanded that this assualt was illegal, as well as their refusal to report on my behalf in a mental health and substance abuse facility in which they were responsible for me and my safety, they gave me a ticket home to CO before my "stay" was completed, and told me, "case closed, goodbye." I believe they knew it would be hard for me to gather my bearings at home and report this from half the country away. My PTSD was so severe afterward that I am now in care of several doctors. I injured my back and nerves, and PTSD is acute
