Just took Step 2 CK — felt terrible after the exam. Anyone else felt this way?

I just took Step 2 CK and honestly felt like I underperformed. A lot of questions felt vague or like 50/50 choices, and I left feeling pretty bad about it.
My practice exam scores were around 240–250 range, but I’m not sure how predictive that really is compared to how the actual test felt.
For those who already took it:
Did you feel similarly after the exam?
Did your real score end up close to your practice scores, or different?
Is this “feeling bad” common even for people who score well?
Would really appreciate hearing your experiences.
