The unusual depressive mood that Chisato had been experiencing lately, prevented her from going to school.
No, you don't need to put a comma before the verb "prevented".
"that Chisato had been experiencing lately" is a relative defining clause. This clause gives essential information about Chisato who is being referred to. You don't use a comma before and after the relative defining clause.
