I suspect I may possibly have SPD, as I have a lot of noticeable symptoms; sensitivity to the light, sound override, irritation and due to that I find it impossible to sit still and sometimes start biting myself and scratching myself... etc. I go to public school and the speaking in the classroom is overwhelmingly loud to me, and it causes all of these things for me, I start hitting the desk and clicking pens like mad to try and cope but I can't... I haven't told any teachers about this when it occurs, but I'm getting to the point where it's becoming unbearable for me to handle, and I really don't know what to do about it as I really would rather not talk to my parents about it.
