25岁，女性。大学毕业先后找了8份工作，由于处理不好人际关系而辞职，虽每次很努力地干好工作，也希望能与同事相处融洽，但总表现出一副拘谨、不苟言笑的样子，别人都不愿与其接近。并很在意别人的看法和态度。思想压力很大，总认为自己讨人厌。情绪很低落，自卑自怜，敏感多疑，自我否定。因而当别人在一起说话谈笑时，就怀疑他们是在讲她、讥笑她。变得失魂落魄，反应迟钝，记忆力明显下降，无心工作，最后不得不自动辞职，以逃避的方式来获得解脱。在辞掉最称心的一份工作后，彻底丧失信心。不敢再去找新的工作，整天躲在家里不敢出门见人，总是把自己沉浸在过去不幸遭遇的回忆之中，有强烈的挫折感和劣等感。无数次想到了死，怕死而且不甘心就这样死去。

A．强迫回忆

B．思维贫乏
