I couldn't agree more with Marty. It is how you spend your time during moments of grief that can make all the difference in the world. Finding an outlet is very important. For me it has always been my running but for others it might be music, therapy, writing, etc. There is no time frame on grieving, how long you grieve, how long it takes, etc. I am so incredibly sorry for your loss and my most sincere condolences.
