Explain why you feel the way you do to a mature and understanding third party who can advise and lead. This might be a pastor, a fellow Vet, a friend. Go to the offender and show a spirit of love and forgiveness. It sometimes helps me to remember that tomorrow will still come, that my anger won't necessarily add or subtract from my physical life. Understand that sometimes God, in His infinite wisdom, allows situations to come our way in order to help us on the way towards spiritual maturity.
Spiritual maturity includes our correct response to the anger stimulus.
In all out guilt, God has forgiven us. If we obey, Our growth toward spiritual, and emotional maturity is assured, and we'll be on the road to deliverance from our anger, and it's adverse affects.
