She laughed when he told a joke.

She laughed when he commented that she didn't look good.

She laughed when he explained that by she didn't look good,she looked sick.

She laughed when he pointed out the bags under her eyes.

She laughed when he asked if she was getting enough sleep.

She laughed when he said are you okay.

When he left she broke down.

She broke down from all the fake laughs.

She broke down from the one simple question.

She broke most down because of "are you okay".

That's when she broke down.

That's when she knew she had to do better.

That she HAD to get better.

That she had to get better at acting.
