I was groped by a supervisor at UW Madison in Feb 2014. I lost my job due to budget cuts a year later & have PTSD. Do I have any legal recourse?

I was bullied/threatened by a supervisor from January 2011. Human resources did nothing. In February 2014, after being trained on a new procedure, that same supervisor patted my upper thigh several times and told me "I guess you can still learn new things." I went to human resources who said she did nothing wrong. Every time I pressed the issue I got these responses: It is not harassment because she didn't ask for anything sexual. It is not assault because it is an isolated incident. She is your supervisor, she can treat you any way she wants. We aren't going to do anything. One year later, due to budget cuts, I lost my job. The person in charge of budgets was the woman who groped me. I lost my job, she was not punished. I now have PTSD, emotional disorders and fibromyalgia. I was bullied over a 4 year period by the supervisor, including threats. She threatened me and others daily for years. What can I do?
