Sometimes that makes it easier. There is much encouragement for deschooling available in the online community. Especially on the unschooling list and the home-ed list, you will hear stories that will reassure you. Anything else they need to know, they can find out on their own. I really believe this is true.
Unschooled children learn how to learn.
Again, I would highly recommend the hs magazines Home Education Magazine and Growing without Schooling Magazine . They both deal with all kinds of homeschoolers, from old to young, with a leaning toward unschooling. You might also check their websites. Other places for support are the home-ed list and the unschooling list. Quite frankly, I can't see how anything but unschooling works with teenagers.
