one word

there is no one word to encompass everything I am feeling right now

I am prepared:
I had my hair cut short
I took a photocopy of the passport
I bought traveller's cheques
I packed a separate 'necessities kit' in my back bag

still,
I have no way of knowing what will happen

let's just hope that
my back can take all the driving and carrying and lifting
nothing will break (her wheelchair, my patience)
nothing is stolen
there is no road accident

I have no way of knowing and I'm worried
but not that much,
for I know that you're thinking of me

one word: you
