how very frightening all this must be, twistergirl~ often anger covers our fears, it's part of the grieving process. perhaps if you tell Jade that you have never left her, just as she has never left you, it will help. i know i often feel close to people who have 'passed', as if there were some kind of mental telephone call going on.
i hope you find a way to keep your connection to your sister, without leaving this world before your time.... you might learn many things that she will be glad for knowing, too~! stay with us~
