I sympathize with you actually, the first time I played through zelda I stopped right before the temple of time because I wanted to start a new game (I think I had just gotten warioware, or something.) I ended up taking a two month break then I started a new file and played through the whole thing in a week (Didn't do 100% this time, had like 13 or 14 heart containers.)
I love zelda games, but I don't have the attention span for games over 20 hours. C'est la vie.
But, you are close to the end, I would say just stop collecting things and you can speed through it in a few more hours.
