Stress

Today is the last day of April and also the starting of Zhouhui's exam. Really depressed and somehow I cant take it. Zhouhui keep sleep-talking at midnight, begging me don force him.He really don noe how to do. Start crying said he want to study but don understand the words. What should I do? I cut down the revision time with him in order that he will not feel that stress. But this matter somehow don't works. Feel so heart pain.. What should I do? How should I do? I really don noe.
