How can I make my Grandmother feel better? Please help!?

Why don't you see if you can make a collage of her friends that have ped away for her. Maybe include pictures or mementos showing the happy wonderful times she shared with her friends. Then after things settle encourage her to join a cards club or visit the local senior center to make new friends. Most senior centers even have cles like painting or cooking or whatever she is interested in. They even have grief support groups. Good luck! And what a fantastic grand daughter you are for thinking of her. I'm sure no matter what she will appreciate you taking notice of her emotional well being.
