Should I tell someone after only 1 date about my anxiety?

I have been talking to this girl for a few weeks and we just met for the first time at a cafe two days ago and had a great time. Awkward sure, but sweet. She said shed love to meet again and honestly after the date is really when the anxiety and looming feeling of doom set it. I haven't eaten in three days, I can't stop tensing my body and medication is useless atp. Other sources and people have told me to just be honest and that I should ask for reassurance but how do I go about that? I really liked her and want to see her again but taking her texts at face value is so difficult for me.
