as salam alaikum
it is important for everyone to celebrate 'Id by going masjid and pray Salat al-'Id.
If a person did not fast due to valid excuses and fasting would have lead him to unbearable hardship, he should give a fidiyah for every day that he has missed. Otherwise, if he did not fast and he did not have valid excuses, he should ask forgiveness and pay kaffarah.
With prayers for your success.
