Drill Sergeant’s are Mental

I understand the reasons why drill sergeants are tough, we all understand the “you’re an idiot” blah blah blah, but my fiancé is in basic training in Ft. Jackson and drill sergeants are telling trainees that they’re going to make sure they die and that they will die. I would understand if it wasn’t an actual possibility, but a young man just died there in this exact company almost a week ago and it’s making my fiancé worry like crazy, I mean he sounds completely torn apart when we talk on the phone. I may be being sensitive, but regardless there’s a time and place. How can I help my fiancé? I feel defeated and worried for him, but not nearly as much as he feels right now. I want to help encourage him, but how can I top that when they’re heating it everyday?
