How can my mother-in-law apologize when she is angry?

That depends on what your mother-in-law disagrees with. It would be easier if you were angry about your daughter's care just because you two took the initiative. You and your wife, echo each other, show your determination in front of him and imagine a bright future. You can clean up your mother-in-law's house if you have something to do. It won't be long before it gets better. After all, she cares about her daughter. As long as you know that her daughter is doing well, you can rely on others. If you are unhappy because you have no money or give less money, it will be easier. Try to make money, and then throw bundles of money in her face, and she will accept it with a smile.
