I'm so sorry your twin sis died--especially so young and unexpectedly. I, too, have a twin sis, my only sibling. Now and then I think about what a loss I would feel if she died first.

If you need to, then please get support from a counselor or some group consisting of people who have lost loved ones. And we are here, too. I really do feel for you and have a bit more understanding, I think, of what you must be going through.
