How do you communicate with your T that there is something wrong when you can't even identify what's wrong? When there are no words? How do you ask for help when you don't even know what you need help with?

Has anyone experienced this?

I know there's something wrong because of how severe my SUI thoughts are, and because I'm still physically sick from anxiety. But idk what's wrong. And yes, this week I tried to tell my T. Every time I tried, I got lost in the conversation and had to start over trying a different way to explain. It's making me feel insane since I usually am very good at being aware of what's going on.
