Divorce is usually stressful for all of us.

I bet you will do just fine.
Some ideas:
Maybe you could work up a sentence or two that you tell folks, explain briefly that you are under stress and confused, doing the best you can. You can tell them that you might need more time to understand things, that you might need to take breaks when feeling extra emotional, and that you are trying to cooperate.
Are there any little things you can do to help yourself feel calmer next meeting? Have a favorite soda, wear a bracelet you like, anything like that?
Ultimately your attorney and the others work for you, they are part of your team.
Does your attorney know that you are afraid that your husband will try to trick you?
Could a mediator help?
