Continue to be there for her. Drive her to visit his grave and allow her to privately tell him how hard this has been for her. If possible, allow her to go through some of his personal belongings and pick out a few special pieces to hold on to. Talk about him often, just because a person isn't physically with us doesn't mean we have to let go mentally. Although, it has been a year, grief affects everyone differntly, hopefully each day will bring her back to getting on with her life but always remembering what a special person he was in her life.
I lost my beloved due to cancer years ago and still cant cope up with the loss. Many a times feel like committing suicide, i tried to keep myself occupied in the best possible way but just doesn't work. I get irritated and angry easily. I cant understand how to survive without him. Please help !!!
