NJ, not quite similar or as bad as your situation, but last year I was carrying weights in pack up a local mountain to train for Whitney. I slipped and fell and jacked up my knee and ankle pretty good. I had a Yosemite trip planned just days later. Out of sheer stubbornness (and stupidity), I did the whole route up Half Dome and limped my way back...I was actually on the verge of crawling. I recovered, and hit Whitney's summit two months later. My right leg however, has never been the same.
You can do it if you want. Don't short change yourself, but don't do anything that'll jeopardize your well being. I think everyone's idea of shorter, smaller hikes to gauge your ankle's strength and recovery is a great idea.
