I understand. You feel you should not be tearful and scared and that you were to blame for the breakdown of your marriage. I think that being tearful in times of grief is a very normal reaction. You are grieving. You are feeling grief for the tragedy you have witnessed in war, grief for the loss of your friends in an accident, and grief for the loss of your wife and family life. Tearfulness is a very normal and very necessary functional process of grief and frankly mate, if you weren't doing it, I would be asking why. It is no wonder, that in this amount of grief, you question the world and are scared about it. You have been a very strong person and are used to being a strong person. At the moment your body is in a crisis and has temporarily disabled you from being strong because it knows that if you carry on that way you will explode. Your body has emergency stopped you so that you can recover from what has happened so far. Your mind doesn't agree, but its tough toenails. Remember that what you are going through is a process. It will stop. Change will occur, healing is happening, and you will start to feel the affect of that one day.
