As I have a great deal of experience with major depression I can say that you don't understand the suffering involved. There is NO "learning to adjust".
Even for depressives, there should be a "right to die". We experience constant "suffering and misery".
I, like I think a lot of other people who haven't ever had constant pain, think, "Oh, you can learn to deal with it, make adjustments, work around it, etc." I've long suffered back pain, and have learned to deal with it, make adjustments, work around it, etc.
For the past six months, I have had a continuous headache. It gets better and it gets worse, but it's always there. I've tried many of the CBT, relaxation and other methods that are supposed to help you deal with problems--the things that have worked for years on the back pain. I've tried all the over-the-counter headache meds, and a few prescriptions. Nothing works. And, it makes it that much more difficult to deal with the back pain, too.
I have a new appreciation for people who have continuous severe pain, regardless of the cause. There ARE some things that you can't make adjustments to, can't work around, can't "deal with" because there is no relief...sometimes not even with drugs that are supposed to deal with pain. Always before, there was relief at some point from the pain; I'm hoping that something we're about to try will work...but there are no guarantees that it will end my headache.
People aren't being wusses, and people who don't experience pain like that really don't understand...as I didn't understand.
But I think that anyone who is considering an early death, actively (e.g., suicide) or passively (e.g., self-imposed starvation), needs to talk about the choice with professionals and family and friends and consider/try options before taking that step. In that regard, it's like any other big life choice--a new job, getting married, getting divorced, having a child...
