As you work on validation, it will come more naturally to you. And really, it needs to be natural and fluid and not like you are reading some script on how to validate...
That said, with the hypnotist for example, from how you quote it above, it actually does not sound validating. It sounds more like you are asking her to do it your way, and even the maybe was a bit resistant.
Again, remember that what she is saying is how she feels RIGHT NOW. She may change her mind or simply not do it. So validating her is, "I understand you would like to see a hypnotist. I can appreciate how you really want to try to understand why you feel the way you do."
Not leading, not suggesting, leave it open ended to allow her to talk it out if she feels she needs to.
If you feel she is TELLING you that she is going to do it, just say that you understand and let it go. Either she will or she won't, but that is up to her to do something about it.
Hope that makes sense.
How might you validate her CURRENT feelings about Milwaukee?
