Im like that too! haha i feel like im understood. For me to do something i have to be doing 5 other things. Like durning a lecture ill have music on, while reading a book, and hearing a lecture. That semi-helps. Also today, since ive been talking about with my parents lately, My dad belives im making this whole thing up, while my mom is starting to notice these things. That when i was little i DID ask for help and showd signs now that she read into them more. So, hm this is all very intresting to me.
oh about that excersice thing, somedays i just feel like, annoyed and frustrated for no reason. I just feel all weird inside that i just wanna go outside and be let loose. I feel like im comfined. And like every little thing will annoy me. Dunno.

Edit:
I ment to add that i work very fast and im always in like a rush. 90% of the time im the first one doen with a test like 10 min before anyone else. I forget to add little things like this in the process. And when i want to like go or stop something, i get aggravated when i dont, like if im on the phone and i say bye but the person keeps talking, i get snappy. But my mind works like super fast. Like if its something slow to accomplish something, i wont slow down to fix it, i just bam get it done and forget alot of little things.
