sserafim, I sympathize with your frustrations. Regarding Dignitas or Pegasos, they generally are not open to helping anyone as young as you, unless you're severely disabled, for example quadriplegia or cancer or some debilitating disease that can be demonstrated by medical records.(other than mental health issues). Unfortunately that's the parameters (statutory, and in general practice) that they are bound by. For mental health (depression, e.g.), they can help but first they want to see a lot of effort to try to see if there's any treatments that could help; about 8% of assisted suicides are for depression (see link below), but I would say most of those are over 50 years old. Also, Swiss law requires that the applicant be of "sound mind," which is tricky to demonstrate if the main complaint is mental health related. So, for these reasons, most of their assisted suicides are for people over 50. In short, in practice it is unlikely they will assist with a suicide unless the member has attempted to live their life, at least "half" their life. Things may change but this is what we're stuck with for now
Here is a link to a 2014 report (download) on assisted suicides in Switzerland that can shed some light on various aspects. (reasons, ages):
