Technically attempting treatment should be part of that checklist. Just like palliative treatments, this is ultimate last resort of exclusion. Presuming there is any reason it's depression, and one of the risks of depression treatments is increase in risk of suicide. Could lead to the same end, or even kill the patient anyway with other side effects. And when do you decide "garbage" therapies like counseling or socialization fail? In the case above, the problem is that treatment requires the person to be committed, and person committed is declared not of sound mind. That's the catch-22 of euthanasia laws. You would have to change the part "of sound mind". And then the doctors could be sued anyway, because some alleged treatment was missed. Either you trust the doctors made a diagnosis correctly or not.
