Hello dear it seems that the event has caused a lot of embarrassment and anxiety which is hampering your concentration. It is essential to get over with that event. Every individual has their past which can be good or bad, but we all learn from our experiences. Try to take it as your past and think positive about the present and future. Try discussing with someone close in your family or friends to feel emotionally lighter, try meditation and schedule your day to involve yourself in multiple activities as to keep yourself busy and happy. If required professional help, then try consulting a clinical psychologist through online consultation or meeting in person.

Talk to a counsellor about what happened & explore ways to best deal with the situations.
