There will always be some people committing suicide, whether assisted or not (here, it was not assisted as has been noted except for agreeing not to force-feed her).
But, the story I read was when she went last year to seek assisted suicide, she was denied as she didn't fall within the criteria. Okay, fine, but what other help was she offered or given?! And, if someone is suicidal, even if they don't want to try therapy/counselling/psychoactive drugs, if they're not an adult, should that decision be respected or not?
Note, while I'm generally opposed to assisted suicide (not only for moral reasons, but because I think it too easy for people and the state to think, okay, low-cost solution = suicide) even someone in favour may have problems with the manner and ease of it. What alternatives are offered that are, guess what, more expensive and time-consuming than killing them? Or in another context, some people commit suicide because they're denied effective pain relief because of laws and regulations and desire to prevent people from getting addicted (too late...) = let people suffer because someone not experiencing their pain thinks they're taking too much. If someone wants suicide (assisted or not), despite what I or anyone else may think, I'm a lot more comfortable if they've genuinely been able to avail themselves of other potential treatments, but not if they've been denied them.
