I'm new here, 21 years old and newly diagnosed with ADHD and autism. I've learnt about overstimulation online and stuff and I think I experienced it today? I was in my class listening to a group presentation and my mind started racing all over the place. I could hear the air condition circulating, the cricket somewhere outside, the mutters of my classmates in addition to the ones presenting, the chair fabric felt ticklish, I could feel my socks and the songs in my head wouldn't stop. I desperately reached for a mini beanbag I kept in my bag and tried to use it to sooth myself but the fabric on that bothered me too and I wanted to throw it as far as I possibly could. Obviously I couldn't do that. I needed to have something in my hands and I ended up scraping and scratching my hands but the sensation of my handprints rubbing drove me mad. I couldn't breathe and I left the class to stand out near the window to try to catch my breath and calm down. I suffered with anxiety and depression in the past and I knew very well that I just had an anxiety attack. Is this being triggered by being overstimulated? It's happened in the past where I've had full blown panic attacks but now that I know what overstimulation is and that I'm autistic it makes sense. I now knew to leave the situation before things got worse. What's going on? I'm not sure if I'm right with this or if I'm making sense, my thoughts are all over the place. What is it like being overstimulated for you guys? What happens?
