What are your best sources for learning self-hypnosis for TMS pain?

I see that the Pain Psychology Center offers hypnotherapy as one of their techniques. I’m looking to add self-hypnosis to my TMS recovery. I’d really like to find something (for free) that I can try myself before finding a therapist.

I’d specifically like to try it for conditioned responses and fear of pain (i.e. all emotions that connect to fear – frustrated with the pain, angry at the pain, annoyed, etc.).

Are there scripts or audio that are good for this?
