Hey... I know it can be hard to receive scores that are worse than expected. This exam has a considerable amount of "luck factor" on it, so now just relax and know you did your best
You passed your exam on your first attempt and, even though it will be harder from now on, you still have chances of matching! You are not out of the game

Just do your best, with good lors and good CK score, you have hope! I know a person (IMG) who got 201 in her step 1 and matched last year for internal medicine! I am not sure about her other credentials, but I know that she got only observerships (no clerkships) and was a fresh grad.
Anyway, just try not to be demotivated, relax a few days, and move on! You still have chances!! And I am not trying to give false hopes, I know it is going to be hard... But if there are people who manage to match with worse scores then you, why wouldn't you?? It is hard for everyone and the chances are only zero if you give up Happy-2
Good luck!!!
