Please avoid involving others in your decision to end your life. They face potential legal consequences. Consider this -- your country has even banned the PPH book which says a lot about your country's view. Where you live, aiding and abetting suicide is a serious crime—ignorance of the law is typically not accepted as an excuse. Why take that risk for someone else?
It's completely your right to make your own decisions about this, and I respect that. However, involving someone else as an accomplice is not acceptable. I want to emphasize that I'm not judging you at all; I'm actually glad you shared this so someone could remind you to avoid dragging others into it. You might not have considered this aspect in your grief and pain, and it's important to hear that perspective.
Even if they don't face formal legal consequences, the guilt and burden of responsibility they would feel would be immense. While we can't control how others react to our decision to CTB, it's a whole different matter when they become directly involved in providing the means to do so.
Find a way to not involved others...
Lastly, as I mentioned in one of your other posts, the frequency and
inconsistencies of your posts may raise some red flags for people. While I've found this community to be incredibly kind, generous, and supportive, we also want to ensure that things don't end up in the "wrong" hands so I just not foresee people giving you any more than the breadcrumbs you can find on here to help you make your own decisions. I truly hope you understand this is not personal at all. I completely empathize with feeling desperate for a solution, so I'll just suggest that you use the search function more and do your own research on methods and then make the best decision for yourself.
Whatever you decide, I hope you find peace & serenity.
