女,55岁。年轻时性格温和,待人和气,结婚以来夫妻关系一直很好,与亲戚邻里关系也很和睦。这2年快退休时常念叨厂子里的某某在算计她,同车间的某某总与她过不去。后来提前办内退,但不是怀疑邻居在议论她,就是猜疑楼上往自家阳台上扔东西。丈夫劝她几次之后,怀疑其有外遇。从此就限制丈夫必须准时回家,不准其梳洗打扮,一见丈夫收拾自己,就认为要去约会。女儿看不过去说她几句,则认为丈夫将女儿收买,为此伤心欲绝。丈夫将上班之余的所有时间都守着她,持续了1年多,仍消除不了她的疑心,反而加重了她的症状。现在甚至怀疑丈夫要害她,看见他刮胡子,都吓得赶紧躲进卧室还念着;想拿刀子割我动脉,做梦吧,我就不死!丈夫和女儿在同一工厂上班,不允许他们一起上下班。 求助者有
A. 无明显异常

D. 注意转移
