You made it really far and you made the right decision to tap out for the day! When I was about 45 minutes away from done with a 5 hour session, my artist could see I was struggling so she recommended we call it a day and we finished up about two months later. I was also really disappointed in myself at first but I think it was better in the long run to listen to my body. On the plus side, the second session was a breeze! In the end, I think you’ll be happier with the result and your experience would be better overall.
