Hell no. It's much better than outliving everyone you have ever loved or liked. Seeing them die around you while you go on and on seems like a pretty good definition of Hell to me. It's easy to think you want to live forever when you are young and haven't lost many people who are near and dear to you. But when you start losing close friends and worse, parents you love, you come to a very different way of seeing things.
And if you did live forever, what are your alternatives to this? One would be not to love or care for anyone, ever. The other is to keep getting your heart broken when those you love keep dying and you continue to outlive them. Hellish existences, either one.
