Hello there. I have attended classes to learn self-hypnosis techniques about 15 years ago, for medical & emotional reasons. I was very fortunate - my GP referred me to the course, which I received free on the NHS! Many people were there for different reasons, from chronic pain-reduction to help with insomnia, anxiety, panic attacks & agoraphobia, fear of public speaking and to control (or at least reduce the frequency & severity of) epileptic seizures - without extra drugs. Also, to help with confidence-building, minimising ADHD, increasing ability to focus on a task and a huge variety of personal psychological issues.
My own motive, endorsed by my doctor, was to teach myself to relax & reduce my high blood-pressure (instead of relying on medication.)
If you Google "autogenic training" you'll find many sites. I have books on it, by the doctor mentioned on this site:

I have personally found the technique very effective & useful indeed - as did everyone on my course. We all found noticeable & striking results.
It does require work though, and actually DOING the exercises 2ce daily ... there is no quick-fix magic wand that just makes everything ok! I find it heartening to discover that I have the capability (as we all do) to control our unfavourable reactions to the physical, mental & emotional problems we face and function more healthily & effectively. It is wonderful! I was so fortunate to receive the classes free.
Sadly, the teacher passed away, and there is nothing to take his place.
Best wishes in finding what you want.
