It is not yet ratified, and even when it is, who will police it With the increasing of exploration and mining at sea, in all probability, the amount of waste will do.

一般资料：求助者，女性，37 岁，会计。
案例介绍：求助者自述最近半年心烦，睡眠差，经常感到浑身不舒服，做事提不起精神。有时会心慌憋气。去医院检查，未发现明显器质性病变。但自己不相信，害怕自己有病，医生不说实话。丈夫也带她到多家医院，做了各种检查，同样也没有发现明显问题。医生针对她的症状开了一些药。服药后症状依旧，工作还经常出错。由其丈夫陪同前来咨询。
心理咨询师观察了解到的情况：求助者性格内向，家境富裕，工作压力小，生活单调。
下面是心理咨询师与求助者的一段咨询谈话：
心理咨询师：您能详细谈谈您的睡眠情况吗？
求助者：我一般十点左右睡觉，入睡没有问题。就是经常早上一两点钟就醒，醒了就再睡不着，睡不着就瞎想，真烦。
心理咨询师：您烦，是因为失眠而烦吗？还是因为身体不舒服而烦？
求助者：是因为浑身都不舒服。
心理咨询师：您说您身体不舒服，可您去了很多家医院，该做的检查都做了，诊断没有病，这是怎么回事？
求助者：我也不知道是怎么回事。
心理咨询师：如果真有病，您吃了药是不是应该有所改变？可您还总是难受这是怎么回事啊？
求助者：（沉默）……
心理咨询师：您觉得会是所有的医生都诊断错了吗？
求助者：应该不会，不会所有的医生都错，那我可能就是没病。
心理咨询师：您想想如果一个和您年纪差不多的人。既要照顾住院的亲人，还得照顾孩子，还要工作，她会整天想着自己的不舒服吗？
求助者：（点点头）是，忙起来就顾不了太多了，我可能确实太闲了。
心理咨询师：这是不是应了一个说法，无事生非？
求助者：（笑笑）有道理，那我得找点事做。
心理咨询师：那倒用不着，您可以尽情地享受生活。如果真有病，该吃药还得吃药，但不要没病找病。您看我脂溢性脱发，这也是病，我能整天为脱发烦恼，到处寻医问药吗？
求助者：听您这么说我就明白了，我以后只要有事，就全靠您了。
