You're asking someone to engage in the practice of psychotherapy. There's a distinction between doing "personal change work" or enhancing "personal growth" or "human potential" and
treating a psychiatric illness.
I have no doubt that there are people here who could help reduce your feelings of anxiety. I don't think anyone here can legally and ethically treat any disorder.
In as much of the English-speaking world as I've yet researched, the person doing the latter is required to have some sort of license. Licensed professionals will also be subject to some code of code of professional ethics based on which of the helping professions they practice. I'm not expert in the ethics rules on diagnosis and treatment via Internet, which are still being developed, as far as I know.
What you can do is find a qualified professional, local to you, who is willing to use hypnosis either as the primary tool of therapy, or, more likely, as an adjunct.
I'm sure this seems like an undue burden, espcially with all the material that's available here, but the rules are in place for the protection of the public. The idea is to protect people who might be in a very vulnerable state from unlicensed, unethical, unqualified, cackling, drooling, sick, perverted, twisted... ;) ...you get the picture.
Given that you've looked here, you might consider trying the
Kink Aware Professionals list to find that qualified local person.
If you can't find what you need, feel free to PM me, and I'll help all I can.
Good luck.
