The grief after a week is not the same as after a month. It's a memory whose emotions remain raw to this day. Don't be afraid to cry. Tears are a release and an essential part of the grief work. Bear in mind, too, that men and women grieve differently.
Women are more open and willing to cry and talk about their pain.
Men tend to internalize the sorrow and have different styles of coping. Be easy on yourself. There's no rush and no one should put a timetable to your grief. For some, it takes a year, for others, two, a few others, three. Only you will know when you have found a resolution and come to terms with the loss.
