Oh, HECK, no, dear HHG (peace to you!)! I mean, haven't we given them ENOUGH? Why in the WORLD would we even give them CREDIT for "taking" the "best years" of our lives? As long as we're still living, as long as we can still draw a breath... the "best" can still be AHEAD of us. Because it's not about what we left behind, is it... but what lies ahead!
Don't given them anything! Not a single moment, whether of your past... or your future! Look at whatever GAINS you made as a result of your association with them... and absolutely DISCARD all of the rest. Anything that wasn't of benefit!
Otherwise, you're saying your life was in total VAIN. But how can that be? ALL life is of SOME value. So, no, it was not and is not! And so long as you're still living... you can still make a difference, somewhere... somehow.
NO ONE should use the WTBTS... or religion in general... to stop living... if they are still alive.
Take BACK your life... and start LIVING it!
Again, peace to you!
YOUR servant and a slave of Christ,
