Hi there filip!
Stay calm and be cool there is absolutely nothing to worry about here.
The choice is yours. You decide what you want to do, and don't to be talked into anything by anyone.
Think about what you want.
The doubt is all perfectly normal. I can, and I am sure many others on this forum have had the same experience and it fades in time and with furthur research.
Ask yourself though, 'why would a loving God kill everyone that isn't a Jehovah's Witness?'
Not very likely is it?
Now you can buy yourself some time to think about things by asking for a break from meetings for a while. Or saying that you are not going to go to the meetings for a while. The choice is yours and they can't make you go.
But explain that you're not going to do anything that they'd consider wrong either. You just want a break to think about things.
I don't know how they'll take it. They seem to be doing quite well at the moment. Could be that they thought something more serious was the matter and when they found out that, that's all that was the matter with you ,
they're quite relieved.
Think now, before your 'little chat' with them. Decide what you want. Stick to it.
They cannot make you do anything that you do not want to do unless they threaten you. If they do threaten you, I remember someone posting a reply to you earlier, you could ask why JWs are persecuted in other lands. They'll answer more or less, that it's because they're sticking to their principles and authority figures are trying to force them to do things they don't want to/or don't agree with. You can turn this into your situation. You don't want to.
But remember. It has to be what you want. Not what we say or what they say. What you want. Make sure you know what you want before you go into the 'chat'.
Good luck! Let us know how it goes!
