Death is often confronting and most never really see it enough to get used to it, as used to it as one may anyway.
Just take your time with it, remember who he was as a person and in your life and allow yourself the time to deal with it in whatever time it takes.
Doing that always..nobody will be like him... I stopped watching his pic anymore, just tobget rid of the pain...but alwsys kept him alive in my memory
