Is my grieving process normal? It's only been 3 days and I'm hardly sad. ?

My uncle passed away about 3 days ago from suicide. I am 20 years old and never lost anyone close before him. Although I hadnt seen him in 6 months we were pretty close while he was alive. When I got to the hospital he was still alive and I stayed with him until he died, holding his arm until he took his last breath. For the next 2 days I was really upset and constantly crying but today I have hardly been upset at all. I went in his bedroom and just felt at peace. Is this normal? Am I numb or just content with knowing that he wants me to be happy?
