Are you asking whether there is life after death or just how to deal with grief? If you are asking about an afterlife, we all have our beliefs, some think there is something else and others think there is nothing after we die.
If you are asking how to deal with grief after a loved one dies I think the answer is we all deal with it in our own way but the only thing most people agree on is time. I have lost both my parents and it is hard to lose people who have been there all your life but grieving is something we all have to go through before the sad times become happy memories. I personally cry a river when I am grieving and it really helps as bottled up emotion just makes the process harder and longer.
