Wonderful answers thus far - and no smart remarks from the retards, which has to be a first!
What you have to remember is the Westerners are very bad at death and grief. After a period of discomfort for those around you - say six weeks or so - they like to pretend that everything is back to normal, and you can carry on as before.
This does not happen.
You need to view the concept of grief correctly.
Grief is not a train on a track, moving forward, each day a bit further away from the pain, and closer to a pain-free life.
Grief is a boat on the ocean. Some days it's calm, your sail is up, your engine works, you are chugging along. Other days a storm blows, your engine is gone, your mast is shattered, and you are at the mercy of the current which will pitch you where ever until they feel like leaving you alone and powerless again.
So remember, some times your pain will be manageable, and sometimes it will be raw beyond bearing, and these feelings, and everything in between can last for seconds or weeks.
But equally important to remember - the intense rawness gets less with time, and the periods of acceptance get longer and longer.
You must go with your emotions, and allow yourself to feel what you feel when you feel it, and don't be diverted by the 'stiff upper lip' attitude - "You should be over it by now ...".
Take your own time, and peace will come to you.
