It is not that time heals you as such, because even after so much time has passed, remembering the loved one causes a lot of nostalgia. Time teaches us what no one ever teaches us: to face and accept the most difficult and strongest moments of life, and it is as I say if we were educated without fears and we were told from an early age that death is a natural process in us and that it is inevitable we would accept it better, of course accepting does not mean that we will not be sad for a while mourning our loved one, but it would not be so traumatic.
