I shall always remember with gratitude the e-mail you sent me when you knew of Jane's death. No one but you knew my sister so well and loved her as her own family did. Only you could write that letter. It brought me comfort, Diana, when I needed it badly.
Thank you from the bottom of my heart for your e-mail and for your much kindness to Jane during her long illness.
I am very happy that my e-mail can help you. I am very sorry for Jane's death. As Jane's friend, accompanying her through those difficult days is what I should do. We cannot believe Jane's death, but we still have to live on. I hope you can come out from the pain as soon as possible and live happily every day. That is also what your sister want to see. I wish you happy every day.
I'm glad that my e-mail brought a silver lining. As you said, I know Jane because I have treated her in my heart as my family. So I know the pain of losing a family member. I am eager to stand with you at that time in the mind. I do not want you to sunk in sorrow, and now what we need is to treasure what we have.
Heart with you!
