Some might think this morbid, but the fact that I just keep hitting my head has become a joke with almost everyone at my school. People will be like "Oh, don't do that you might hit Margarite in the head!" and I will be sitting all the way across the room. Others have designed marshmallow helmets for me.
It is so weird to people that they can only act with laughter or sympathy and I encourage the laughter.
I even wrote a sonnet about my headache

Master Mine, Master Mind,
Master of My Mind

He thinks they are my foes and to be feared,
He will not let them come without a fight.
They come now wishing me to be all cheered,
He will not let them come, he holds me tight.
Their mates approach as well, but he holds fast.
None can or do approve his jealous care,
Demanding he retreat and die at last.
The pang of his reply tells me, “Beware!”
He claims his right of me for my mistake.
He banishes all hope of other joy,
Impossible to leave and him forsake,
My constant friend, to him I cry “le roy!”
His the gift which is beyond all measure.
His the gift, my much beloved treasure.

He is the headache.
They and their mates are those things which everyone else thinks are great like light and sound, but in me they cause headaches nausea and dizziness.
The mistake is my first concussion caused by me falling off of a horse that I should not have been riding.
The gift is all those things that this trouble has helped me to learn such as patience and understanding for those who are ill or how to grow in self despite pain.

Just trying to take joy out of pain.
Good Luck All!
