Willing to share if/what’s your plans? Do you live in a somewhat helping country like Swiss?
I’ve a similar view for myself but my GF find it creepy and don’t want discuss it, yet. That’s embarrassing, I don’t want to cause grief by a surprise disparition.
Practically speaking there’s NGOs that can help and even send kits after a (long) checkup. Inert gas asphyxia seems to be a classic as it’s fast, painless and quite cheap/easy.
