Can Hartford spy on me again?

I have been on LTD with the Hartford since the fall of 2009. I was diagnosed with bipolar in 2004, and worked for several years with this condition. In July 2009, I was diagnosed with Multiple Sclerosis. Last week I was contacted by someone affiliated with the Hartford to meet with me in my home and assess my ability to work. The man arrived early, and when he was informed that I had bipolar as well as MS, he replied that he did not know about my mental illness. This was shocking to me as my psychiatrist has sent paperwork to the Hartford a multitude of times. The main reason I am unable to work is the unpredictability of the two diseases, and the adverse affects some of the medication for the MS has on the Bipolar (I explained all this to him). I was honest with him about my functioning. At the end of the video he showed my a 5 minute video of me going into a local supermarket, taking my boyfriend’s grandmother to a doctor appointment, and stopping at a deli to buy lunch. Now, the “investigator” did say that I did nothing in the video that I told him I couldn’t do. However, as paranoia is a symptom of bipolar this has made my conditions worse. Do I have any rights? Will they spy on me again?
