Grieving my little brother

Just posting to let y'all know that I don't know when I'll be posting or stamping again. I found out yesterday that my 29 y.o. brother passed away over the weekend. It was very unexpected and they are saying it was natural causes. Explain that to me? How does a 29 y.o. die of "natural causes"?? I don't understand, it's just not right. I keep repeating that "it's just not right". I'm just so deeply saddened by it. He was in the Army, stationed at Ft. Drum. He was a medic and had served over in Afghanistan. He had a great sense of humor, killer blue eyes and knew how to push your buttons. I loved him and was very proud of him but I don't remember the last time I had told him so. We hadn't talked to each other very much over the past couple of years. The last time I'd seen him was in May when I went home because my stepdad had passed away. The last time I heard from him, which was through a myspace message, was in July. I can't stop crying about it. I don't know what to do, think or say. My poor mother ~ how do you bury your husband and only son within 8 months of each other? It's not right. He was due to get out for medical reason around the end of February. He had gotten approved for 100% disability. He was going to help my mom move her furniture and things. He had just sent her a check for his portion of the storage unit they shared. It's just not right. I finally move closer to home. He was going to be moving back home. We would've seen each other more. He would've been able to get to know his nephews finally. He talked about going back to school. It's just not right. I'll miss him with all of my heart and will always regret not talking to him more. Not for lack of trying, but there are no excuses. Lee, I love you and am proud of you and will miss you more than you'll ever know.
