I knew of five: An older sister who was looked up to by many as a model JW who endured a serious illness which involved the blood issue. Years later she was found in the garage with the car running. She did not leave a note.
A brother who was about 39 years old with two children and a wife who was not a JW was found in his car with a hose stuck in the window. He left a note saying something about not being able to live with the stress of being in a divided household, refering to his wife.
A young man about 25 who was studying with an elder friend of mine hung himself in his back yard. He was battling drug abuse and was being told by this elder to just concentrate on the "truth" and his life will turn around for the better, no more worries...blah, blah..As I stated, I knew the guy he was studying with and sat in on a few of the study's he had with him. What the guy needed was direction to professional help, but that was "forbiden"..what a waste. The guy's older sister was a JW and she was feeding him the same crap about the "Truth" being the answer to his drug addiction.
Tink's Dad shot himself a month after we got married, in their living room right in front of her mother. He was never a witness, but made many attempts to try and become one. He was constantly pressured to change his life by joining. His health was very bad and was in danger of having both his feet amputated due to diabetes. His last words to her mother was, "I'm sick and tired of being sick and tired".
Tink's brother's wife had a twin brother to shoot himself. He got involved with someone in another country and got caught. He shot his self the day before he was going to have to go to a judicial committee.
Those are only the cases I knew personally about. I have however, heard of countless others who for the most part suffered from depression or just couldn't take the pressure from being involved with the JW religion. It's very sad to say the least.
