sorry mate. my nan died bout 9 weeks ago and now my grandad had to go to a home and he is broken without her i know how terrible you feel.
i guess i feel lucky that i had a great relationship with my nan and grandad just like u have had. my grandad loves jungle book that always makes him laugh. u have to remember the good times and try to forget (as best u can ) the bad times.
i hope the year gets better for you mate im sure it will
