Thanks, @chika46 for the introduction of such a controversial theme. Here in Austria we, as paramedics, have to do at least eight hours a year of training (theoretical and practical). Every year Suicide is one of the themes for training courses.
No, we don't practice killing ourselves there. (Sorry, my paramedic black humor broke through.)
I think every living human should have the right to end their lives the way they want to. With this statement, I'm going against the general opinion, and I would never talk to a suicidal like that or to other paramedic colleagues.
In the last few years, I had maybe two or four patients who thought about suicide. Thankfully, we (I'm talking about a paramedic team) were there to prevent it.
All of the cases I'm talking about weren't about human beings being in the "end" of their life (by the end I mean in their 70s or 80s and further). The youngest case I can remember was a 16 years old male. He cut his veins open the real way and not the way you see in movies or tv shows.
As I've said, I think it's okay to end your life the way you want it to end, but only as last resort for an unhealable disease. Everything other can be managed!
Your girlfriend left you? Don't worry, there will be another. You went bankrupt? There are ways out of it.
Only a few situations in life occur which would quantify as a reason to stop living and by few I mean none.
If somebody feels like it's not worth anymore seek out for help! Life is always worth living no matter how bad you feel.
