It is pretty amazing the number of times I have read about people on this site going traveling for extended periods of time. Usually they will post about being concerned about an upcoming trip, but then return having had a very positive time. Not everyone of course can do it, but many do.
A year or so ago I drove a motorhome, for the first time ever, from the east coast to the west coast so my Dad could see the Redwoods and Pacific Ocean before he lost his sight completely to macular degeneration. Granted, I was traumatized from how awful my Dad, Stepmother and husband got along...but I damn drove that motorhome! :shock:
It is amazing how sheer willpower...and in my case, a little medication...can help one overcome some of their most major life obstacles.
I hope your trip does work out for you. Begin to see it. It can happen.
