Well, you can use that fear to drive you forward and think of ways to stay away from the proverbial rat race. You have already got a head start in many ways because you've been used to that way of living for a while.

Stay as free as you can, the "world schooling" sounds like the best option there as you can literally have a home anywhere? But having half a year to travel does also sound good so either one of those is a good option :)
