I don't know why this is getting down-voted. This wouldn't be the first AMA where someone pretended to be terminally ill.

Pre-purchasing a funeral is fairly common in the US, especially for elderly and terminally ill patients. You don't set the date, but you pick out the casket, etc. and make arrangements for the bill. Your country must have something like that. It might be something you'd want to look into, and have that last bit of control.
