My Unum case workers told me "people that have seizures work everyday. What makes you any different?" I feel useless

I have worked my entire life and in May of 2011 I became ill with seizures, which my doctor can’t determine why and has had me off work since, because they come several times a week and leave me very confused and sore. And my Unum case worker (whom has no heart) said to me people that have seizures work everyday, so what makes you any different? I said because they can’t figure out what’s wrong and the fact that I am having so many of them, my employer feels it’s better that I not work with them until these are under control. She advised me to find another job then… so I asked to speak with her boss, whom I advised of the way she was talking to me and that I was depressed enough without her rude mouth. I advised I had lost my truck and my home since all this. His advice was for me to contact the churches and help offices in my area or to go to ER if i felt like life wasn’t worth living anymore. They just talk to you in a way that makes you feel useless
