Woodland,
I think this is a sore subject for many.
Personally, I have tried to recapture some of those "lost" years and experiences. I would like to think that it is never too late.
In my case, I was raised in the Truth, and started to fade at age 21, when I decided that I wanted to study architecture and go to college. By the time college ended 5 years later, I was 26 and was fully OUT the door. ( RUN ! RUN! and don't look back!) In that sense, I am lucky to have accomplished that much. The real test came later when I tried to assimilate myself in the real world; not so easy.
I realized that I had grown up in an insulated vacuum, of sorts; a rarified sheltered world of Pioneering, ministerial servant responsibilities and Eldership as the ultimate goal. This was all "out the window" and I was not able to cope with the real world and real responsiblities. It took 2 years of therapy and deprogramming to ease the transition; and several more years for the fog to lift. I had th ehelp of many good "worldly" friends.
There are others who woke up years later, and blame their devotion to the "Truth" of robbing them of a direction in life. I cannot blame them for feeling bitter or resentful, I would feel the same. But life goes on and is worth living and pursuing ( at any age) a dream. An open mind and willingness to proceed is all that is required....
