I'm no expert on the Sedona method/Release technique, but I've experimented with the techniques they offer enough that I might be able to help.
AFAIK Larry Crane and Hale Dwoskin were both students of Lester Levinson, and some time after he died they went their separate ways, formed separate companies, and both allude to themselves being the "real" continuation of Levinson's work in their advertising. Good to know that it's not just NLP that results in dramatic splits and separate "camps"!
My experience is only with the Sedona method. I listened to the tapes about ten years ago, and I still own the book, which contains all the essential ideas of the audio course. I have never had any instant, amazing, dramatic results with the course, however I do genuinely notice a sense of lightness, energy and freedom after working with the questions for 20 mins. In fact sometimes there are real insights, and I find myself laughing. I just try not to do it in Hale Dwoskin's tonality or after the seventeenth "could you let it go" I start to feel I'm trapped in a new age retreat with windchimes and dreamcatchers! (apologies Hale) I also don't fully buy into the theories and models they provide of how the process works. But that's another matter...
The particular objections you raised will most likely be dealt with by your course. For example, you may be right - the job you want to take might not pay you sufficient money. And you may need to thoroughly consider all the options. But worrying - ie. running through negative scenario after negative scenario, steadily building up your cortisol levels and repeatedly asking yourself "what if this happened" and "what if that happened" may not actually make you a clearer, wiser decision maker. You might consider whether you really need to worry and feel bad to be able to objectively consider the advantages and disadvantages of the job. Does worrying reliably help you make the best choice? What would it be like if you could make your decisions, even ones where there was an element of risk, by feeling calm, good, and carefully evaluating the pros and cons? Anyhow, you should find releasing during decision making is part of your course.
Also, even if you feel stuck, you can notice what it's like to sit with the stuckness, to sit with the wanting to change it, and allow yourself to want to change the stuckness as much as you do. It sometimes reminds me of a westernised form of Buddhism, sitting with what is, and ultimately loving
what is, rather than latching onto memories and projections of the future. But I'm still a beginner at that one!
Finally, when I began doing it I think it's fair to say I felt as blocked as you have done up to now. But if you stick with it, you might well find a gradually increasing sense of opening, spaciousness and calm that can take you by surprise.
All the best,
