Second, your mother was injured, wasn't she? Your mother also went to the hospital, to identify, report to her and sue her!
Third, whether it is a civil lawsuit or a criminal lawsuit (there are restrictions, but your family situation is suitable, hehe), counterclaims can be used, that is, the plaintiff can be accused in turn in the same case. If she wants you to pay, you can also ask her to pay.
Look at your situation. Everything wrong is half right and half wrong. Tell each other what I wrote above when mediating a bad relationship. Don't be soft It's usually over. No big deal. Don't worry.
