I feel there's still people who don't understand depression.
it's only one step from "oh, they should have known better than commit suicide" and
"oh, why don't they just get up and go out, everybody gets a bit down"
As it's been said before, people commit suicide because they see no other option.

My own tuppeth:

Suicidal ideation can vary from fleeting thoughts ("if I could just walk out into traffic and get hit and die"), to planning (making a note for your loved ones, making a plan of how to do it and about how you'll be found, collecting paracetamol etc), to action (either attempted or actual suicide). The person affected is usually mentally unwell. It's not seen as rational to kill yourself (hence the stigma around euthanasia) unless in extreme circumstances (eg taking a bullet for someone).

There is always someone who gets affected. Sometimes the person committing the suicide has thought about this (in terms of manner of death, or leaving a note), and sometimes they haven't.

In some ways, it's human nature to be indifferent to suicide if it's not someone close to you. Otherwise we'd be mourning at every death and there's something like 2 people per second dying. Do I personally care that Joe Bloggs, 98, died last week? No. I didn't know who they were. Do I care that Joe Smith, 17, jumped from a bridge? Might reflect on the meaning of life, death and circumstances that would have led to that decision, but it'd last a few seconds at most and I'd move on. Would I care if someone close to me died? Yes, certainly.

Most of us probably think along similar lines - we care if it's someone we knew or if it impacted on us directly. Most of us will be indifferent about the death in the same way most of us don't mourn constantly for all those people dying.

I agree with that. The bit I don't agree with is getting somebody else to unwittingly kill you and they then have to live with the consequences of taking a life.

If the trains were self driving and nobody else was involved in the act, it wouldn't be so bad.

I know that they often can't think clearly and that they don't consider the effect they will force on other people through their act. But at the end of the day, it is still a selfish act to force somebody else to kill you.

I think that part is a good point. It's how much leeway you give someone who is mentally ill in making those sorts of choices, it's seems very selfish to a rationally thinking person with a certain level of moral thought patterns, but to someone who isn't in their right state of mind and suffering they aren't thinking about those consequences and future suffering for someone else, they just want to end it.
