I don't buy your argument or see any evidence for the assumption that feeling better now will somehow hurt you in the future. Have you gone through a period of feeling terrible and then feeling better? I have, quite a few times, and I've been as close to understanding how important now is when a person has only a few months to live as I think one can be. When my spouses was dying, what mattered was how can he have the best quality of life right now? Whether that was pain meds or homemade borscht or a movie at 2am, that's what we did. Not worrying about what might happen tomorrow, or next week, or next month.

I feel so much better now than I did four years ago. And I've had other periods of feeling better after feeling worse. No question for me that feeling better is sort of a skill in itself, that I've gotten better with experience as well as help from therapy. But I think it's the opposite of what you believe, that feeling better now helps you feel better in the future.

And if what you're really driving at is suicide, I think that's a personal choice that can be invoked by a person at any time for any reason. I don't have any moral issues with it. I think it may not be a strong basis for making other life decisions.
