You are considering a massive change in lifestyle that will severely challenge you physically and mentally. Consider giving yourself abundant preparation and transition time.

Consider Plan B. Is there another alternative that will suffice? It sounds like most of your journey now is internal: seeking your right path in life. A physical journey may support you in this effort, but maybe doing something less dhallenging would free up energy to get enough internal movement. It is possible the rigors of survival on an epic trek would take up most of your energy, leaving little for the more important journey within.

Review the Appalachian Trail thru-hike information available on the 'net. One thing I recall is that they mailed or shipped supplies ahead to stops along their route. Another is that they traveled very light.

Good luck!
