All I can say is that Heaven would be much, much better than a life like that (for myself, anyway). Whether Terri really wants to live like that or not is the question. Michael Schiavo says she doesn't, while most of the rest of the world who wasn't there when she supposedly stated her wish says otherwise.
That is true and her husband has ordered that no therapy that might establish some sort of communication with her be tried.

You put it well to say "for yourself" but even that is an opinion since you have neither been in Heaven or in the condition Terri is in. I look at the statements some people make here and think "what a living hell it would be to be them." But maybe it's not as bad for them as it appears to be. It might not even be that bad if I thought like them. It's an uninformed opinion.
You either believe life is sacred, in all circumstances, or you don't but none of us knows what death will be like.
