What do I do if my friend killed himself?

I came home from play practice yesterday at about 3:30 or 4:00 pm. I saw a bunch of cars in front of his house. There was a cop car, a pastor’s car, and a few other cars. The first thing that came to my mind was, “DID DUSTIN DIE?” I saw this policeman come out of his house. I knew that something bad had happened and that he did not like it because he had a sad look on his face and he just looked like if there were to be any wind, he would fall down. My mom then told me that she thinks that Dustin died. I started crying just thinking about it. I then went and stood at the window waiting for some sign saying that nobody at his house got hurt and that everything was fine over there. Then there were these 2 people who came out of his house with a red body bag and someone was in it. It is just driving me crazing and making me have random crying spells just thinking about life itself… I don’t know what to do. I loved him so much! I am now left without him... I FEEL SO NUMB! im crying now...
