Well, it's a journey you have to make (or not) for yourself, I think. I think if you still have hope then you're probably not ready. Personally I've found that getting older generally slowly kills the hope :/ It's kind of impossible not to have it still if/when you're young.
I don't think anybody here WANTS to ctb, it's kind of like the other options are worse. I think most people would rather something changed somehow so they could enjoy life or not be in pain instead. For me personally, it's not a great option. It makes me feel sad. But I'm never getting better and I don't have any kind of quality of life, so...
I'd say explore everything before you make up your mind to go (or not). Go travelling. Live and work in a couple of foreign countries. Study something that interests you. All kinds of things to do (and I've never had any money, it IS possible). I've found doing some kind of charity work makes me feel a bit better (personally I work in a rescue centre because I love cats, but seeing the results of human cruelty to them can be quite hard). I would say I don't include having children in that, unless you want to adopt as I don't believe in bringing more people into this miserable place, but that's just me.
I guess that's the only thing I'd say, especially if your health is currently good - mine isn't and that's the main reason I've had enough. I didn't get much time to enjoy being healthy - started getting symptoms at 30. You just never know when you'll lose your health. Obviously, if you are in the same boat that won't help. I know it's hard to appreciate something that you've always had and has always been there - I certainly didn't, so maybe that's not helpful anyway.
Difficult to really offer any advice without much info. So I guess that would be my thing, make sure you've exhausted every other option first.
