Not only do they deny you the right to euthanasia, but they also force you to work. I honestly don't know what to say; I am speechless in the face of such an atrocity. Isn't there some way to make them understand that you are totally disabled? Some medical report? I suspect the answer is no, otherwise you would have done it by now. And maybe you did, but they ignored you. Sigh...
Or maybe you could outright report them, because I think it is criminal to force a person who is completely incapable of working to do so. However, the laws of your country may also be working against you, so they may not pay any attention to you. If you don't mind me asking, what country do you live in? Don't answer if it makes you uncomfortable.
