No and I'm sorry if that sounds cruel. For starters- I don't have N. Plus, even if you have a substance- how can you be certain it's the real deal until you test it? Which you probably won't want to do until you are nearer using it- so as not to break the airtight seals. Secondly, it's illegal- you would be assisting a suicide. Thirdly- suicide I feel has to be a solitary road when it is not clinically assisted- I have the deepest sympathy for everyone here who wants to take their own life but I feel like they can be the only one to make the preparations and do it. Just like I eventually may/ will. Forthly, I might change my mind further down the road- even if I had improved, I'd still want a way out later if things turned bad again.
If it was a family member or a very close friend who were incapacitated and unable to 'help' themselves- then that might be slightly different- although I imagine by that point, clinically assisted suicide would be an option- so I hope I'd help them via that route.
