Okay friends! I have to stay off the accuweather site. It is driving me bonkers

The temps are up and down. The sad thing is that first of all, I still have two weeks, second, the is
NOTHING I can do to change the weather.
I promised myself I was not going to stress about...
a. Crowds- So far doing okay on that one.
b. Packing. - Not a suitcase around...yet
c. The weather...seems to be my sorry source of pre trip stress. Why? Mostly has everything to do with the whole packing thing.
d. Poly Lonhouse location- Maybe think about this a little too much? But again, I can request, but really can't do much about.
It is all part of the planning "illness" I know.
I hope you are all not suffering from the same symptoms!
