Sorry to hear you failed. I also failed back in August with lower performances in question skills/professionalism and rapport and passed easily my 2nd attempt. It doesn't mean you won't be a good doctor but make sure you take it again before 3/24 to receive your score between 4/25 and 5/23, especially if your school requires it for graduation.
The 2nd time I really just read the USMLE website because it tells you exactly what they're looking for. For questioning skills, the only thing I could think that I didn't do was summarize for any of the 12 patients. The 2nd time I summarized between history and starting exam ("Now to summarize, you came in having...., is there anything else that I missed"). Just doing this change made me go from lower to higher performance. I'm sure I missed other stuff the first time but summarizing is definitely important.
For Professionalism/questioning skills), I made a dumb pneumonic CSI FEST for (concerns, summarization, impact of illness on life, facilitating statements, expectations, support systems for patient, and transition statement. I just addressed these with each patient and received higher performance the 2nd time in professionalism. Also, never leave a patient room early and spend a lot of timing closing/counseling. There was a study that showed amount of time spent correlated with a higher CIS component

As for the match, is there an adviser who has your interest in mind at your school you could talk to? Did you check the automatically release box? What specialty did you apply for? If you don't release the score and get a passing score before starting residency you probably will be fine but it's not something many people have experience with so it's tough to say.
I didn't release my step 2 score and have finished interviews without anyone asking about it. If I match in March I don't even know if the PD will see my failed attempt or not and if so I don't think it would matter that much because I passed my 2nd attempt and didn't break any rules by not releasing my score. Also, my adviser recommended I keep quiet about it.
