I had a friend and his brother that are like brothers to me, their mother always jokes that I was the third son she never had. 2 years ago in high school the one got into a car accident and lost his life. Even when I was standing there looking at his casket I still didn't feel or believe he was gone. When I go to hang out with my friend I still feel like I'll see him there, it's been 2 years but the feeling remains that he's not gone I even randomly feel like I need to check my phone for a text from him but I feel like that's just him saying hello from the great beyond. So yes I feel that way even after 2 years, it's awkward, wierd and uncomfortable at times but look at it this way they might be gone from the physical world but as long as you remember them they're never really gone. Sorry that was so long, I didn't know if it has happened to you and if it did I figured it would be helpful to hear someone else's experience
