Hi Courtney,
Sorry you are going through this, as always Mark has some wonderful advice.
I am pleased you are seeing a doctor tomorrow, definitely mention what happened today as it's very important.
I can only speak from my own experience, I had a concussion almost 8 months ago, I've had a lot of problems, I had the most severe headaches I'd cry, couldn't walk straight, think straight, slow in every way, on and on...this went on for months.
Take extra special care of yourself, take things slow. Good luck tomorrow.
