I'm sorry that they haven't been supportive. I am sorry to hear about your grandfather. Anniversaries are always hard but it will get easier in time It is not uncommon for feelings to resurface.

As for them, it could be a number of reasons and not all of them mean that they don't care. They may have felt uncomfortable or not known what to say, not felt that it was their place or just not realised it is what they should have done. There are some people who don't know how to react to a situation like that. Not that any of that makes it any easier on the individual grieving. Sometimes saying something is better than nothing.

I know personally when my grandfather died I did become angry at someone who seemed to be very insensitive to me grieving and needing time. It took time but eventually the anger faded.

Take it easy as you can over the next few days. Give yourself time to grieve and feel what you need to feel but also try to remember the good times.
