Grieving is perfectly natural when someone you love dies. Your own personality and background will affect the way you grieve. Some people weep, others become quiet and some will need to talk to someone. Weeping in private or in public is a common experience at this time, there is no need to feel embarrassed. Your family and friends really do understand since most are suffering, or have suffered, just as you are.
Lean upon your loved ones and your faith, if you have one, and be glad for the happy memories which make parting so difficult now, but will sustain you in the future. Likewise don’t feel guilty if your feelings are of relief that one who has or would have suffered is now relieved of pain. Your grief will come later, but you can rightly rejoice in the removal of pain and suffering.
Whatever your feelings now, take heart that the experience of those who have lost loved ones will help you through this time.
