I would be stubborn and fight my hardest, toe to toe, till the end. I've cheated death more times than I can count and I don't plan on letting my life go until something beats me to utter shreds. So long as I have one eye and a half a brain that works I can still watch hockey, that's good enough for me! My good friend killed himself when he was 19, and our high school exchange student from Denmark did the same thing in her late teens, both because they had Crohn's. They hurt a lot of people, including me in doing so. Many of the loved ones left behind will never be the same from the grief they experienced. Some are even angry. I really think that had either one of them sought professional help, they would likely still be here. I hope you find a better option. No offense intended, just my opinion and experiences.
I have endured some very serious health problems and heartaches, as have plenty of others. The problems lasted for years at a time for me, and I'm glad to say that I have made it to the other side of the dark and nasty inner storm caused by IBD. I just don't see death as a viable solution to the difficulties in my life. To me it's an oxymoron, really. I may not be in perfect health, or rich in material possessions, but I'm still here. For that I am very thankful.
