Hello,
Poor you.. have some ideas maybe they will help you.
First check if she is not sick or not teething.
And then maybe she is scared of sth what happened during the day, so the solution is to speak with her in the evening, about all her day. If she can't tell you , you can tell her, with questions and help her to answer. And then she will not be thinking alone about this later. You will tell her that everything is all right etc.
Hope that everything is fine until now:)
