Mobbing/emotional abuse/post tramatic stress

I have been working for my company for 9 plus years in which time I have been through a lot. I have given someone cpr that there was no hope in reviving, put up with abuse out of one of the other supervisor, and when reported I was made to switch shifts. I was not allowed to work over on other shifts for a couple of years because this person was on the shift, but regardless I was the only one in the company who was not allowed to work any other shift. They let this woman go and brought her back in December. I have had this woman tell people that I followed her and her husband home from work which was a lie. Is there anything I can do?
