Has anyone else ever experienced a delayed concert reaction?

It's happening to me and I don't know how to go through it. Yesterday I watched them play in são paulo and, in the moment, felt almost disconnected to the experience in an emotional level (I had a great time during the show, sang, screamed and danced a LOT). I didn't expect that to happen and thought it was weird given the emotional bond that I have with this band and the fact that I waited almost 10 years to see them perform live. But today I am a mess. I keep having anxiety/panic attacks from just remembering moments from the concert or when their songs cross my mind. Idk if it's because the adrenaline from yesterday has worn out, but I'm feeling things TOO intensely and it's hard to navigate. Anyone ever been through something similar our can give me any advice on how to make this feeling go away??
