The sky is not falling.
Failure is bad but its not the end of your journey.
Please read the post of others which I read here.
Its so motivating.
I am not able to post the links because I am pretty new here.
Search for my experience 3rd attempt in the usmle step 2 forum.
Google Search for "multiple attempts and matched 2016 took 7 steps to get the residency hope this helps". you will see a post in the student doctor forum website.
