In the countries where euthanasia is commonly practiced, there are huge ethical discussions about it and the more you learn about it, the more complex it gets. It turns out, that if you get dementia, your personality changes. The new person you may become may not want to die, even if they cannot judge the situation adequately. In any medical situation a no means more than a yes and, in general, that is a very good thing.
I share your opinion that I would rather be euthanized than have my loved ones go through the whole process. But it really isn’t simple.
Asking the Internet for medical advice is never, I repeat: never a good option. The best advice possible that you can get here is go see a doctor. I say that, because there is no way anyone here can do a proper assessment of your situation, so that is the only safe advice. of course, statistically speaking, it’s not likely to be something that will kill you, but we simply cannot tell from here.
My advice: don’t be alarmed too much by all the horror stories you can find, but take it seriously enough to let a qualified health professional take a look at it.
