Hello. There are many well researched therapies for depression, anxiety and phobias/ fear. CBT is a therapy that is very effective and medications such as SSRI treatment are effective as well. Hypnotherapy is not very well researched and there are very few well trained hypnotherapists.
Next Steps
I would suggest-
Please consult a psychiatrist who will give you the available options and then you can decide which is best for you.
Health Tips
Sometimes hypnotherapy may worsen some conditions. So it is very important to get professional help before you go to a therapist.
