I struggle a lot with sensory overloads. Too much noise too much lights too many people and I've been told it's down to anxiety. But I'm not scared of them??? Its not just that I struggle with. I'm working with my school to up my skills on socialising and identifying others emotions, I'm very restless and hyperactive a lot of the time and then can completely crash and become really lethargic either when overwhelmed by sensory imput or just being really exhausted. Yes I can admit I'm anxious due to the anticipation of being in a situation that I can find overwhelming but I just dont think they the whole answer. 

Ive looked into autistic spectrum disorder and originally that's what my school believed I had but now there under the impression that it's just anxiety. To me the symptoms just dont add up. 

Any advice?
