You'll have to drink water, or you'll die in 3 days. I can improvise the only other things likely to be needed (ie, protection from the elements and bugs), assuming that I have normal clothes to stand in. I could boil the water, too, if need be, but obtaining-making containers is a big PITA. In really bad bug country, I'd take enough bug-netting to cover me completely, instead of the water treatment.
It's not hard to make a fire with a fire-bow, using shoestrings and local wood. It's also easy to make a debris hut, using bark, pitch, clay, woven grass or reed mats, and playing with the pitch of the roof to make it shed water. A week is nothing, in mild weather. You can easily do completely without food for a week of just lying around. Plenty have gone a full month or more without eating at all.
Wth would you need all the tools FOR, for a mere week of lying around, anyway? You can find or break off branches for shelter-firewood. It isn't like you have to be constantly on the move. You oughta try keeping bugs off of you with nothing but a knife or an axe sometime!. :-) Smoke is as irritating to you as it is the bugs, and it floats with the wind, just like the skeeters do. Some species of skeeters can't fly more than 10 ft or so above the ground, and the breezes tend to be more active above the ground, so sometimes you can sleep relatively bugfree in a tree-platform.
