You don't sound arrogant, you sound beat down. You do sound like you could use the help of a counselor. Would your wife be willing to go to marriage counselor? Hopefully there is a way to negotiate.
You need to take care of your health. I hope you can develop a healthy interest or two for yourself. Hopefully, you can maintain a relationship with your children, although you said one was married so does that one talk with you? Please try to hold on, build up for yourself. Don't let that horrible JW world beat you down. Try to find a friend or two, on line here and hopefully locally. Take a class of interest. Be healthy!
