Bad day vent

Anyone else just need to vent to anyone who will listen after a bad day? We took my 6 year old to a featival to see his favourite band. Total sensory overload. Could not cope! We go to loads of festivals and this is the first time we have really felt it. He fell off a high stool face first onto a concrete floor. Got up and wouldn't let us check him just bouncing and jumping on the lights made by the disco lights. It's like we weren't there. Been hyper and in his own world all day. Then got upset as his dad was getting frustrated with him and telling him off. Just wanted to go home, I'm sad but I don't know why. We are on our way home without seeing the band we had come for. One of his favourites that he would never see otherwise as its the only child friendly gig they will do 😞 he's high functioning and has dyspraxia and usually copes ok but today has been hard work
