One thing that really gets under my skin these days is the trivialisation of mental illness and the constant belittling that people like me can suffer. I have recently been pleasantly surprised at Dignitas's plans, due to their new-found treatment of mental illness as if it were physical illness - no more messy suicides, no more 'rescues' and no more horrible, crippling failures. You see, although people don't seem to realise it these days, mental illness is every bit as painful, disheartening and life-wrecking as physical illness is - perhaps even more so in some cases. Yes, I have a disorder which causes me to contemplate suicide most of the time. But no, in no way does that mean my wishes are not completely sincere - I've been thinking about this since I was around 9 years old or so (don't expect me to go away anytime soon, though). The thing is, just because someone is 'out of their mind' enough to think about suicide does not mean they should be coddled like a child and told that they now cannot make an informed decision about the matter. In fact, the very fact that someone has thought about suicide, even if they have a mental illness, to some extent justifies the act of suicide! What I mean by this, is that anyone with such a degree of ennui is obviously suffering to a large extent - large enough in many cases, that it would actually warrant the act itself.
The other complaint that is shouted almost at verbatim is that mental illness is 'curable', while terminal illnesses are not. The problem with saying this is, treatment isn't as simple as just a course of antibiotics, or an antitoxin in the bloodstream - it's a long, gruelling process that eventually culminates in a lot of lost years, a lot of lasting scars, and the pain of knowing too much - of knowing what the world is really like. Yes, you can make the choice to stick it out. But at the same time, one could quite easily think that the wait isn't worth it. A large, unparalleled amount of suffering for a slightly content few decades? Should we make people suffer for that?
But I know that there probably are a lot of people who might change their minds about wanting to die, so I am definitely in favour of waiting periods, counselling classes, etc. for people who want assisted suicide. But I am most certainly not in favour of any long-term suffering.
