I want to:

I want to talk to you.
But I need to leave you be for a little while.
I'm sorry that I am sometimes poor
at silence.

i have much to say.
but this is not the time to say it

I have been thinking a lot
feeling a lot
and i know that I am at a loss
not being able to share it with you.

Enjoy your trip.
I hope it is what you need.
