Accidental insurance should be easy to get. It covers, well...accidents. Getting full comprehensive life insurance will likely be near impossible though. If you are lucky, sometimes you can get it through an employer, of course, only if they offer it (that's how I got mine). Even if you do get it through an employer, most life insurance policies from employers are not portable, so if you leave the company, you lose the insurance. That is one of the reasons I actually took my present job, they offered life insurance up to 100,000, no pre-existing check, and it's portable, so if I leave, I can keep it up.
I definitely wish you luck, and if you, or anyone else, knows of a place to get real life insurance, keep us all informed, as that is something anyone with cf can use.
