Don't worry! It takes a bit of practice! Before your dough embarks on the long rest, (if everything went right) the texture of the dough should be fairly smooth and rubber-like. You could also try using lukewarm water instead! Oh, and don't save on the kneading process (it's important for gluten formation). Lastly, when rolling out the dough, be generous with the oil, it makes the dough more pliable.
