Dissociation whilst on a date

Went on a date with someone, caring understanding and diagnosed with cptsd. We had a lot to talk about. Date went on for 8 hours, near the end we entered a very busy restaurant, I started have symptoms of anxiety, hot and cold flushes, heart racing, unable to talk or hold a dialogue, felt so uncomfortable, I randomly said about getting the food to go alluding to going home, I knew what I was saying and the connotations that went with it but couldn't stop myself. Its the next day and I feel so embarrassed, I continued texting her after the date and spoke to people about what had happened. I'm still dealing with the anxiety but think I stopped dissociating anyway

This hole thing has put me in a depression.

I want to tell her what was happening but idk if I should continue contacting her. I feel like a weirdo
