Hello @TheJuZShoW
I understand that feeling of grief never really going away. As another member said,
"We never really get over the grief that we feel when a special person has left our lives, but we generally do learn to live with that grief."
In a way, I believe it is a matter of working out how that special person would wish and encourage us to live our lives.This seems to be in line with what @wellwellwellnez is alluding to, with respect to their grandfather, with the comment:
"when I do commune with him, my impression is usually him reminding me of the "real world".
My mother passed away nearly 3 years ago. She lived with me for 10 years before she died. I am still recovering. Part of the process of recovery, for me, is to consider how Mum would like me to continue with the life that I have. I, in turn, have others for whom I am a meaningful part of their lives and I believe that I need to live the best life that I can for them.
I do not know if there are other people in your life for whom you are special. Would you care to talk about any other people in your life, whether they be family or friends.
It is definitely true that,
"Life is and everything in it is not the same."
Though it may bring some strong feelings to the surface for you, you might like to look through the thread "Trying to stay Sane" in which @Anastasia has described her recent experience. Each of us experiences these events in our own particular ways. So when we read of other people's experiences, they give us ideas that we can either accept, adopt or allow to pass, in accordance with how we are responding to the events in our own lives.
With Care and Concern
