im not sure if this is relevant a t all, but when walking around a shopping centre i can feel very confused and unable to coordinate myself or think clearly. im bumping into things and cant think straight and say odd things. my light sensitivity gets bad. i can feel a bit dizzy or overly overly lethargic. im not sure if his is a physical thing or a really bad outcome of over intense surroundings with adhd
This sounds like sensory overload to me. I don’t know if it’s related to ADHD specifically or if you have a sensory processing disorder (it’s a common comorbid condition). An occupational therapist might be able to help you figure it out and find ways to deal with it.
