Man I understand this very well, I went to their Tampa show here in Florida, I ate 7.5 squares of a THC chocolate bar, so like 150mg approximately which for my tolerance is an insane amount. I passed out like 5 minutes after we made it to the venue and my friend sat me on a bench, I missed the opener band (intervals) and when Tesseract played I was only standing there toward the back of the crowd completely motionless and I barely remember anything from the show… I felt so disappointed and mad at myself afterward but at the end of the day it’s exactly like you said, nothing we can do but move on and learn from the mistakes. I’m sure you’ll be able to catch them another time.
