That is exactly how I felt. Meetings 3 nights a week, field service on the weekends, study the other nights of the week. Prepare for talks. Prepare for field service. Read your literature. Then don't do this, don't do that, don't do the other. Can't associate with worldly people, but witnesses don't want to associate. No large gatherings. Watch our speach, only talk about upbuilding things, don't tell anyone if you don't agree with the society on certain things. Then you get cretnoids who do their best to stamp you into the ground and tell you your not spiritual enough.
It didn't matter what you did, you never felt like you were acceptable to God. I always remembered that scripture "probably" you may be concealed in the day of his anger. So with all this martyrdom we still weren't guaranteed life.
Being a sister I didn't have the same the responsibilities of an MS. But yes ...I'd have to say I had that sinking feeling a lot.
I used to think what was the point. And finally realised there was none.
