Since you need help with your unstated problem, be sure to seek a qualified professional, licensed with a masters or doctorate degree, in your area. Call others to inquire about the person's reputation. Call them first and hear their voice. Ask of their specialty. Years or experience does matter usually. Then work together within their method for change. If they are able to use hypnosis due to training, then they can decide when and if that would benefit. That's the best way to do it.
Remember in many states, anyone can call himself or herself a hypnotist. And, there is no regulation about “Ericksonian Hypnotist” - to some….if they smell money in it they will say they are it! (I’m sorry to say).
I sorry to have to be someone who acts as if to give you the run around. However, be more specific and I might be able to answer in a more specific manner.
How do you determine if hypnosis is right for you? It probably isn't. Why? Hypnosis is a modality for communicating. It is no better and no worse than the context of waking state. It is no more effective as a tool than the ability of the speaker and listener. It is just another way, a different way. Sometimes the heightened awareness for internal experience will help a person facilitate the change they are working for...as will practice, spot-on explanations, demonstration, etc.
Why in the world would someone think they needed hypnosis? I suspect that if you think that you need it (from the get-go), you are probably not a candidate for it. While this is not always true, it is certain that many people think there is a magic, a deeper path, a value, a benefit, a shortcut, or a way to change, that requires less involve involvement from the client...and hypnosis will provide it. They get that idea from here and there - media, less professional therapists, hype, myth, etc., you name it - and they conclude hypnosis is what they need. Let the person who uses and understands the use of hypnosis in therapy decide if it can aid the process.
If you need a referral in you area that uses hypnosis as an option, contact the Milton Erickson Foundation, Inc. 602-956-6196 and they can at least point to the nearest. You can also contact the American Society for Clinical Hypnosis and inquire (847) 297-3317.
