It's not something you ever get over...and if you did it would mean something was wrong with you. Parents should not outlive their kid. Especially when you know the cause was negligence and avoidable. No apologies necessary...I think we all grieve with you. Our military families represent the best of us as a nation. I pray you will feel God's hand on your shoulder.
Bruce was able to put my thoughts into words. God bless you.
