bitterly

One evening Marilla, coming in from the orchard with a basket of apples, found Anne sitting along by the east window in the twilight, crying bitterly.

Bitterly did she repent the license she had given to her imagination.

I was bitterly disappointed, Diana.

I cried bitterly, and asked Miss Stacy to forgive me and I’d never do such a thing again; and I offered to do penance by never so much as looking at Ben Hur for a whole week, not even to see how the chariot race turned out.
