Deep breaths my friend. Don't freak out yet. Take it easy and relax. Do something to occupy your mind. When does your third year start? Just go do something till the scores come back. No sense in climbing up a mountain when you don't have to.
In reality, 94% of people pass the test. I took a NBME with no studying at all mid-way through 2nd year because my school offered it and got a 180. You might feel like you failed, but I highly doubt it unless you completely screwed off by not reading FA at all or something. I think you will be pleasantly surprised.
