Disclaimer: I myself am not currently suicidal, I'm just looking for a discussion about the act from a philosophy standpoint.
What does lewd think about the morality of suicide? Should people have the right to end their own lives? Is it a universally selfish act, or can it be a reasonable choice?
In my own opinion, each person's life and the circumstances surrounding it are different, so they should be treated as individual ethical dilemmas. It's neither universally immoral and unreasonable, nor universally moral and reasonable. Therefore, it shouldn't be provided as a "right" that everyone has. On one hand I do think there are cases in which euthanasia is the right thing to do, but on the other, I do think most people are incapable of appraising the value of their own life. While they are the only person experiencing it, they're also a biased observer.
Using myself as an example, I know that I'm mentally ill, and in a way that negatively influences how much value I place on my own existence. However, I also know there are logical, external reasons I suffer. What it comes down to is, how much of that suffering is based in circumstance, and how much is a direct result of my illness? And me being the sick person, do I really have the ability to make that distinction soundly? My own appraisal is subject to things like delusional thinking and negativity bias, just as much as other people's perspectives are external to my subjective experience and therefore potentially unreliable. Even if the distinction could be made accurately, and even if it were true that my suffering was all directly caused by my illness, the ethics of my suicide would still depend on something that's yet unknown--that being, whether my illness can be sufficiently mollified with intervention, and if so, how quickly.
