I know... very vloody inconvenient this BC. No manners or timing ??
Do not worry much about Uni... it will be there still when this is done.
Right now concentrate on the surgery, healing and whatever therapy is aftwrwards. Do not take me wrong - worth still making plans and going ahead just do not forget to give yourself a bit of breathing time and slot in some rest and relaxation pauses in there.
That July getaway sounds lovely and providing it works arround surgery and post op appointments I would not be cancelling it... I only wish I took a week to get away between surgery and chemo to recharge batteries instead of trying to cram to much work in there...
