I think the email sounds perfect. Very professional. You put in enough info without overdoing the details. I am all about planning, I have to have things in place to the finest detail, so I get what you are doing. Not knowing where you'll be or what is going to happen can be unsettling and anxiety provoking. I personally don't see it as avoidance, I see it more as care-management. Kudo's to you for taking control of the future.
