Under the terms of Theocratic War Strategy™, the Elders™ will think nothing of lying to your faces and telling you that you will not be DA'd for having nagging doubts or for not being sure that the Faithful and Discreet Slave™ is directing Jehovah's People™.
If my husband ever made an appointment to meet with the Elders™ and I was not interested in meeting with them, I would not be there when they showed up.
Definitely plan with your husband ahead of time what you will not discuss with the Elders™. If you don't feel confident to discuss doctrine with them or policies of the WTS, then DON'T. Make it off limits.
Make it about behaviour that you have seen exhibited among the JWs you know.
You can be Stumbled™ by unloving attitudes and actions that have happened to you, it can make you question whether JWs really are Jesus' true disciples. If they say it's an "isolated situation" but overall, worldwide JWs aren't like that, you can say "But when we meet a Catholic or Methodist or anyone else in Service™ who has complaints about unloving behaviour within their particular congregation, don't we say that it's evidence that they are not Jesus' true disciples? We don't look at the relief work or the hospitals or the food banks that their church - overall, worldwide - has done to help others, we condemn other churches on the basis of individuals' actions within the church. How is that consistent with Matthew 7:1, 2?"
If they insist on pressing the issue, you can throw down the Conscience™ card: It bothers your conscience and feels hypocritical to go door-to-door and invite people to join this religion, when you don't even feel welcome or loved within the congregation. The Conscience™ card is a very powerful thing - it's a "conversation stopper" - JWs have been trained to respect the Conscience™ of others and they will back down immediately.
You can be discouraged by personal circumstances. The prospect of losing all your friends for being true to yourself is "discouraging". You wouldn't be lying.
You can be depressed. You need them to be patient and understanding with you. It's a difficult illness. Sometimes depression goes hand in hand with panic disorders and you feel heightened anxiety and panic when you are around other Witnesses or at the Kingdom Hall. Every time you go to a meeting, it feels as though more burdens are being heaped upon you and it makes you feel that no matter what you are able to do, it just isn't enough for Jehovah.
Those are all things that have worked for other folks on JWD.
