Here in Belgium the system is possible the most permissive in the world. People can fairly easily get a doctor to euthanize them due to a loss of quality of life, even for purely mental issues. I recall a rape victim, young woman with a husband and young kids who did this. One of the victims of the airport bombings here in Brussels chose euthanasia because she couldn't overcome the mental trauma of that day. People who are paralyzed for life (but basically stable) ... the list goes on.
I assume there is a similar service wherever you are.
Nah. Here in the US the religious people worship other people's suffering. It makes them feel better. (I'm serious, there is this whole story of Jesus suffering were it's the point of everything)
You have to come up with your own solution.
This varies by state, of course. My dad used prescribed medication to end his own life, quite legally. Oregon.
