My Teacher Told On Me!!?

I Know it sounds Petty, but the lady asked what I thought of her cl so i told her it was a waste of time. Then she told the guidance counselor i dissed the students and school. I wouldn't give a care cept the counselor has to write my recommendation to a gifted school. I went to cl today and it was unbearable, schools almost over, do i write a letter of apology, or just ignor her for the rest of the year?
