I can so relate to this! my grandfather died 4 years ago... i know exactly how you feel. and only time can heal the emptiness in your heart, one day, the pain won't be as bad and the next and the next, until you will eventually heal. im rambling, as usual (lol), but i hope you understand some of wat im saying... stay strong and take care.
