Very sorry for your loss.
Not sure if this helps but it can't do any harm I guess: I first saw spirits of "deceased" humans when I was 2-3 years old and I've come to learn that nothing or noone ever dies, what we perceive as death is instead a continuation of life..just in another form.
In my experience our memories, experiences, thoughts and emotions remain intact, and our love connects the 2 densities of life in a bond that can never be broken.
I'm not saying that it's wrong to grieve or that you should let anyone tell you how to feel and for how long... just saying that even tho such a 'seperation' leaves us feeling like we're left alone in a pit of despair, we are really never alone - our loved ones are only a thought or emotion away.
