My bad. I took it as she was quoting you.
I've been there and know this all too well. Lost 3 family members in a 4 month period, with one of those being very tragic w/ young children left behind. Didn't take the relationship seriously, until the final stages, but I was blinded by everything else to see that she had already checked out. She left after the second death. No contact whatsoever. That was a tough fvcking period of time. It's been 4 years since and it's still tough here and there. I also have trouble letting things go, that are out of my control. I do believe, that there is a silver lining in every cloud and you have looked this thing in the face. It has had a tendency to make normal problems and fears seem so trivial. When you watch someone you love pass away in your presence, there is very little you fear after that, with one exception and that is, not living this one life you have been blessed with to the absolute fullest. Your problem is a simple one to fix. It's not an easy one, but the answer for me has been reframing my mindset and perspective on nearly everything in my life. Good luck brother!
