Was it a problem in the first place?
Sometimes validation is enough.  At the end of a session some people say, “You mean I’m not crazy?” “So, it’s o.k. if I’m still grieving the loss for example, (of my  marriage) a year later?”  Sometimes, having a sense that you are entitled to feel the way you do is enough to give a person confidence to cope on their own again. My job is to do myself out of a job.
