How does one deal with a sudden death in the family?

There has recently been an unexpected and sudden death in my family. I don't want to get into specifics but suffice it to say this person was very healthy, under 60 and led a very vibrant and fulfilling life. A life of chesed, a life of Torah and and got nothing in return. This person was suddenly taken from my family through a tragic accident, not an illness. Many people will surely miss this individual. The people who came for the shiva were some of the biggest torah figures in the torah community in NY. Including the Noviminsker Rav, Rav Reuven Feinstien, Rabbi Faskowitz, Rav Dovid Cohen , Rav Zolty etc. even more would have arrived had that not been away on this holiday weekend or the summer ( Eretz Yisroel etc). The funeral was packed with people from all over. Even on a holiday weekend there must have been 700-900 people present. I was suprised by the amount of people from the music business who came to visit the family
( not that they all came for me): Shelly Lang, Ike Walkover, Mendy Wald, Shloime Reich, Yeedle, Shloime Dachs, Yisroel Williger, Ari Greene, Binyomin Ginsburg and others. At almost no point did people stop visiting till late into the night. We heard stories received letters from the patients who were so upset and wrote about the tremendous hakaros hatov they had for this person. The help the family received from neighbors family and friends as well as outstanding organizations such as masaskim is not to be believed! I'm not sure how I'll be going forward from here...
