Hey,
Your story just sound so familiar. I fell of a horse and also suffered from a concussion. I get headaches everyday, whenever I read, watch tv, use a computer, are in a busy room, stress too much or worry about stuff. This means I can totally understand your problem. I can't concentrate either and feel very sorry for you. Try to avoid headaches (easier said than done!)

I totally get your frustrations and the thing you said about the cast. People want to be able to see your hurt, they want to make sure you don't fake the whole thing.... This can be horrible!

I don't have a lot of tips or anything, I jast wanted to let you know... YOUR NOT ALLONE!!!!!
