THE LAST STRAW

You may have dealt with an unpleasant happening for a long time, as things worsened you couldn't accept it any longer.
The last straw is an idiom which basically means the final problem that makes someone lose their temper or patience. If an event that follows a series of bad experiences makes you feel you can't tolerate it anymore and you finally decide to leave it or do something to change it, you call such an event the last straw. It means you are very angry, you've exhausted all your patience and tolerance and you have had enough.

You can no longer put up with it. It is the final irritation that exceeds your capacity of dealing with something that you have been tolerating for a long time. For example, a teacher tolerates her notorious student and keeps warning him, but when he back answers her in front of the whole class, it is the last straw as she no longer has the capacity to deal with him patiently and gets his parents to meet her.
