I know that there is help available and all that bullshit, but I want to know if there is a legitimate threshold when it is okay to kill yourself. When is it okay to give up and face the fact that a bullet in your skull will gain more traction than your wellbeing ever will? When is it okay to drop from a society that continually endeavors to divide? Is there ever a point where I have no excuse for not killing myself, and struggling would make things worse? What do philosophers or psychologists say about this?
There are a few countries, The Netherlands for one, Switzerland for another, that allow citizens (and non-citizens for Switzerland ) euthanasia for people with severe, non terminal mental health issues.
You could look into the criteria they use.
