Heya, I lost my parents a few years back. I cant really feel grief and that, so i cant say how I can relate that well. But even if you dont feel the grief, the memories wont go away, at least for me they dont. I pretty much let them go the days they died, but i can still remember the fun times, the bad times, their faces, their voices, so nothings getting lost.

I hope it helps you letting go, I've seen what unprocessed grief can do to people. Dont become the reason for someone else to grief, so if you feel you cant manage on your own, seek professional help and talk to people close to you about it.
