She is supporting and encouraging others to commit suicide, a mortal sin. If she was a Catholic, she excommunicated herself by that act, unless or until she repents (and takes the required penitential steps). As far as the 82 y.o lady, none of us know the mind of God. I'd like to think He would not judge her too harshly under those circumstances. But from what we know... it's not good. Remember, Catholics don't believe that death is your last chance, so there is hope even after -- I find comfort in that.
Where did she do this?
