Don't bother reading the comments under that man's in Switzerland youtube video, they are cancerous, people with no empathy who can't understand our suffering.
I looked up that Emily documentary (Belgium though?), and she still had to go through a lot to get the permission. I just wish it was easier to get permission. Few months of "evaluations" or trying to "reason" with you, and if you still want it, go ahead, despite if you in your mid-twenties, mid-forties or whatever. And I am sure in the future it will be. But for those of us hoping to go away with a professional-assisted method that could be too long. Another 10 or more years of suffering, or alternatively pulling a less pleasant method.
I believe this is the video @ManWithNoName you meant
It says out of first 100 applicants with the mental illness, 48 were accepted. I guess it is easier doing it in Belgium than in Switzerland, but still an uphill battle. Probably would need to prove you were diagnosed years ago, went through half a dozen of medications, that you have a good support network - friends and family, functioning life, etc, that you are not killing yourself over a "momentary issue" as they might deem.
Personally I have been suicidal since I was a kid, and had normal family/school environment, nothing to do with my suffering. I know what could at least alleviate my suffering, and that's what I have been focusing since I was young, until now my mid twenties. But some people don't achieve this their whole lives, so it's not like it's a given I will. And on top of my suicidal daily thoughts it makes it much harder. Even if I had a crystal ball and someone would say I could get there in 10 years, I would opt not to, as every day for last 15 years or so has been painful, even the so called "good days". And as days go by, it's getting harder and harder, especially last few years. I had my first attempt 4 years ago, and I had 2 attempts last year.
Yet I never have seen a doctor/therapist, NHS in UK is not reliable for mental health. Private therapists are costly, and reading up about them, not that good either. I have talked to friends for 5 hours at a time and that doesn't help reach any conclusion, as I have been through this more than half of my life, so I thought through everything already. Some therapist 1 or 2 hours a week wouldn't even be able to get through anything in that time.
But because I didn't get any official diagnosis, they probably wouldn't grant me a permission in Belgium, even if my suffering is no lesser than those 48 who were accepted.
