She [topic-は] I [subject-が] bad [quotative-と] screamed.
絶叫する ('to scream, to shriek') is the most extreme verb in the screaming spectrum — 絶 ('extreme') + 叫 ('shout') — far stronger than the everyday 叫ぶ ('shout, yell'). It belongs to dramatic or written contexts: action novels, horror scenes, news reports of outraged crowds. The embedded 私が悪い ('I am at fault') uses 悪い not in the sense of 'morally bad' but in the everyday sense of 'in the wrong, to blame' — 私が悪かった is a common apologetic phrase ('it was my fault').
