If it was as easy as that she would never have gotten her request approved. It is extremely rare for someone at her age to have her euthanasia request approved on account of mental issues. Hell, it is near impossible to get your request approved for this at old age, let alone when you are in your 20's or 30's. So please be careful with comments like this, as having exhausted all available treatments is a prerequisite and there are a lot of them. Mental healthcare in the Netherlands is in a fairly shitty state thanks to 20 years of budget cuts and 'let the market solve it'-policy, but it is not so shitty that we just resort to killing off troubled people.

If medical professionals would even have had the slightest feeling that there was a way remaining to get her some semblance of a normal life, she wouldn't have been eligible.
