Hope you are doing well !
Just think of the millions of married couples who divorce after so many years together. Just think of all the years you wasted at jobs you didn't like and now you find one you like. Just think of the many years spent with friends and then you no longer speak to each other or hang out.
The Watchtower life is the same. Things change and what was important in your life then is no longer important now. Try not to think of all the hours spent in book studies, field service, assemblies, Kingdom Hall meetings, personal study and Bible studies. It will drive you insane if you had the count the hours that you spent working for the WTBTS. They are nothing but slave drivers. If it ain't you slaving for them, they will find a new one.
My uncle was an Elder for close to 50 years and died with no '' paradise '' anywhere in sight. Who knows how he felt at the end of his life after dedicating all his life slaving for the WTBTS?
