【案例一】：

一般资料：求助者，女性，45岁，个体老板。

案例介绍：求助者的儿子患有先天性心脏病，十多年来她把大部分的时间和金钱都用在了为儿子看病上。她认为儿子患病是由于自己年轻无知，怀孕期间吃药造成的，为此一直自责，异常痛苦。有一次儿子生病，半夜到急诊室就诊，当时医护人员正在抢救一位心脏病病人，忙不过来。求助者当时又急又累，突然觉得透不过气来，胸闷、心慌，非常难受，觉得自己也得了心脏病。因此非常紧张、害怕，浑身颤抖，呼吸急促，心跳加快，当即晕倒在急诊室，经诊治后症状缓解。后来又有类似症状发生，住院检查，未查出明显器质性病变。此后经常发作，每周大约3—4次，时间持续数十分钟。发作时无特定时间地点场合，也无明显发作征

兆，可自行缓解。多次到医院就诊，服用过镇静类药物，但仍时有发作。发作时头脑清醒，不发作时，生活、工作大致正常。目前求助者不敢一个人外出、一个人独处，怕自己突发心脏病死了。知道自己不一定患心脏病，但没法控制。情绪低落，曾对家人表示这样活着真是受罪，还不如死了。

心理咨询师观察了解到的情况：求助者身体健康，性格较内向，对自己要求很严格，做事认真谨慎。对孩子照顾得无微不至，把孩子看成自己的生命。
