Plausible accidentality

[Railcar$Coyness3]

I haven't seen much discussion of this topic here or anywhere else. I think it's my right to end my life if I have truly weighed all the possible futures and determined that the expected value of suffering outweighs the expected value of meaning. At the same time, I know that my death would be hard on my immediate family. I only see them like once or twice a year, so the practical impact on their lives would be low, but of course the emotional impact would be huge. I think it would be an order of magnitude even worse if they knew it was intentional. Therefore I feel a sort of ethical obligation to have my suicide be plausibly accidental, to spare them as much of that burden as possible. It seems like almost every method discussed here does not consider this. I do a fair amount of climbing and mountaineering, so the thing that seems most believable would be to go jump somewhere that I would go climb anyways. I just really struggle with the cowardice of actually jumping, and I'm not sure I can bring myself to go against my survival instinct enough to do so. I feel much more capable of drinking something alone and in as peaceful a way as possible. Does anyone have any insight into plausibly accidental methods that are also more passive and peaceful?
