Having suffered from deep depression myself it is easy to judge people when these things happen but when you are in the pits of deep despair you are not thinking normally. I thank God and my parents for my deep religious beliefs that I knew that God had better things for me and that lead me to my path of recovery but not until I was almost ready to give it all up. I pray for him , his family and the community he touched. He sounds like he was a very important person in the community and he didn't even realize it. Always keep the positive memories of him close to your heart because it will keep that part of him alive. My thoughts will be with you all in Sioux City as I ride this weekend.
Peace David
