Do it anyway. Lead by example. Over time, you might find they become more used to the idea, particularly if they have someone who can help them with the paperwork and organisational side of things. If you can help them financially, so much the better.

If you are successfully revived, you will have plenty of time to make new friends, and start a new family. I'm not meaning to sound callous, but its not unheard of for people to lose their families and eventually recover. I'm doing everything I can to persuade my family to sign up, but its up to them to make the final decision.

I'd give my life to save my family, but I wouldn't kill myself if I found myself alone.
