A friend of mine cured herself while hiking the Appalachian Trail. Pretty much you're putting yourself in a completely different (sometimes magical) environment, mentally, physically, and emotionally. Six months in the woods and around mother nature and trail folk will change you.
If that's something you'd consider, come to America for 6 months and hike the trail. Start in March/April -- go north. You'll spend about $3000-$3500 USD. Map of the trail
