I'm arranged to be married by next year

As far as suicide goes, hypothermia is pretty high up there on my list of the best ways to die. Only real downside is the requirement that you live in the right climate, or travel to it. It also takes quite a bit of willpower I suppose, since that initial body shock is pretty tough, but after that it'll be too cold for you to really think or feel anything. And you can even include some sort of hilarious reference on your tombstone about turning into a popsicle or something.

I agree, this is a good one. Mainly because I could pull it off in my backyard, sure, but it's still up there. Just make sure you're not found for quite some time. Crazy people feel the need to save others they see in trouble.

I've always thought jumping in front of a large, fast moving vehicle would be nice, as well. Access can be tricky, depending on where you live.
