My condition is not (as far as I know) terminal at this point, but it is most definitely chronic and the symptoms and damage seem to be worsening with no end in sight. I have neurological Lyme disease and additional tick-borne co-infections that have progressively rendered me more and more helpless as multiple systems as well as my brain itself has been severely destabilized and thrown into wild dysfunction because of the infections. I'm a slave to the constant onslaught of persistent symptoms that have made it so I am unable to work or live independently, and I've given up investing hope into them resolving or improving. Have had no success with treatment thus far.
So to answer your question: I think you will find a variety of answers from a variety of contexts. For me personally, ideally I'd take CTB into my own hands and elect not to pursue the legal route. On one hand, I am not ready to die, but on the other, I am being forced to live and perceive through a narrow tunnel of near-constant suffering. I was dead set on CTB a few months ago, but after procuring N and doing a couple of practice runs, I've realized that I'm trapped; I'm unable to actually go through with it. I am 40 and have no financial debt, no friends, no children and no spouse/partner, so have no real worldly attachments or loose ends to really worry about. The primary reason that I can't CTB, other than my own fear and SI, is because of the pain and suffering that my mother would endure as a result of my death. I am not close with her, but she has taken on a massive burden in the collapse of my health as I lost my former life and have had to move back in with her. I have not had a very happy or fulfilling adult life, but she gave me a wonderful childhood and has been there for me throughout my whole life. I have come to realize that I could never be at peace killing myself after the sacrifices that she's made for me.
I'm really sorry that you've been burdened with the endocrine disease, and the pain and symptoms that go along with it. That has to be incredibly difficult to manage and endure. It's so hard to wake up every day from sleep and re-enter the reality that your body has betrayed you.
