Man, I feel for you. I wouldn't want to be in you positon. Can't you get leave? You have to hand it over to whatever gives you faith. There isn't much you can do, but your Dad would want you to keep a clear head right now and keep yourself focused on the job. It's sounds heartless, but if your head isn't at 100% then your endangering your own well being. I spent 4 mos fighting for my life and I pulled through, I really mean I feel for you. I'll pray for him and for you to hold the grace to endure this. Whatever destiny holds you cannot control, just be glad he's not suffering. Know that and let it give you peace for now. That bike will always mean something to you whether you ride with him or not now, he'll always be there when you ride that bike in spirit. Don't forget to keep a clear head over there, I grew up over there and I know survival is a ***** in those Shamals.
Best of luck
