If you had a heart attack, came to in a hospital bed, would you rip out the IV, get dressed and go to work???
Didn't think so. So you CAN SWITCH, it's just that you've become attached to your present circumstances and are not prepared to break free. So stop killing yourself, quit and do whatever it is that you can contribute greatest value by.
That's a rather extreme point of view. There might be contractual obligations for him to stay (being sued isn't nice even if it won't kill you) or personal reasons (as stated in the edits), family, friends and loved ones. "Breaking free" from a family is not what most people want to do.
