WOW (((((((hugs))))))) that is a LOT of stuff to deal with, all with car accidents! OMG! I would, of course, be just as afraid as you are... of course your family has already gone way over the odds... ok? SO really now, it "should" be behind them and you...

Driving a car is a big responsibility, and is more dangerous than flying... but I'm more afraid of flying right now... however, after reading your post, I'm thinking it might be a good thing? Maybe even a helicopter??? Sigh. Sorry.

Do your best. We are already hypervigilant due to the PTSD... and we need to realize this, and well, do our best.
