overwhelm? Why, yes.
Have you ever been completely derailed because a tag in your shirt was too itchy, the grocery store was too bright, or three people tried talking to you at the exact same time? It can feel infuriating to watch other people navigate a noisy, chaotic world with ease while you feel like you are vibrating out of your skin.
You aren't being overly sensitive, and you aren't being dramatic. Your brain simply processes the physical world differently.
Most neurotypical brains have automatic filters that quickly decide what sensory information is important and what can be ignored. The ADHD brain often lacks those filters. The hum of the refrigerator, the fluorescent light, the itchy tag, and the conversation next to you are all processed with the exact same level of intensity. Eventually, it becomes a neurological traffic jam, and your nervous system overloads.
When this happens, you are pushed out of your "window of tolerance," and your body shifts into survival mode: fight, flight, or freeze. You cannot logic or think your way out of a dysregulated nervous system. You have to speak to your body first.
