Is it necessary for a GP or psychologist to refer me?

No. If your concern is of a medical nature, like an allergy or a skin condition, it’s crucial to obtain a proper diagnosis from a doctor. In such cases, it’s essential to continue any prescribed medication. If the issue is psychological, maintaining your current support system is advised, with hypnotherapy seen as an additional form of assistance. In certain instances, I may suggest consulting your doctor or psychologist before proceeding to make sure I fully understand your condition and that I am complementing their existing care.  Any contact with them will only occur with your explicit permission.
