She has gone native and fully embraced the local culture.

She has gone through with her decision to quit her job.

She has gone out to buy groceries.

The alarm has gone off.

She has gone down on her knees to propose to him.

She has gone back to her hometown.

He has gone postal and started yelling at everyone in the office.

He has gone batshit crazy.

She has gone to sleep.

I have gone to bed early.
