There are many free or affordable resources to learn self-hypnosis online. The process itself is not complicated; but when attempting it alone one can miss the mark because they wouldnt actually know what to aim for. Try googling learn self-hypnosis free.
I recommend finding a hypnotist who would hypnotize you and teach you self-hypnosis. The guidance of the hypnotist would ensure effective and efficient learning.
The best online resource I had found was Self-Hypnosis and Advanced Self-Hypnosis by the late Gerald Kein of Omni Hypnosis. His videos may still be available on the website for Omni Hypnosis
