Jack, my deepest sympathies go out to you and your family. Ironically, I met Jessica on this site after I lost my brother a few weeks before Amy passed away. She understood, instinctively, that terrible loss that comes with a sibling. We exchanged several e-mails, talking about our siblings and sharing our grief. Jessica was such a wonderful source of comfort, freely offering support, expressing her immense love for her sister, as well as her gratitude for her own life.
Her spirit surpasses her untimely passing. I will always cherish the "Poem of Life" which she passed onto me. It has sustained me and my family through some rough times. Now, when I read it, I think of my internet friend Jess, smiling upon her family, encouraging you to be strong and to complete your life with your precious children. Her spirit continues to be around you, now and always.

Peace to you and yours....
Libby
