Been to school for 2 days( January) and planning to go back tomorrow

Yes,I’m going to school at the last month(exams) and I have 30 days and then school will end. First of all I am 13. I’m quite young. And I have social anxiety so I can’t imagine going back to school seeing my classmates and I’ll be scared of what they think. And also I haven’t been to school last year(been to school for Atleast 40 days) and stupidly enough for the first day of school this year I told all the classmates I’ll try to go to school more often.I’m so embarrassed 


What should I do?
