Helen, like others who have expressed their opinions above I believe that homoeopathy can help you with your phobias.
However in my opinion it is essential to have a very good homoeopath on a case such as this, and you might have found one, but statistically the chances are in the UK, that you have not.
Can you supply the name of the person which one of us might recognise? Or give a location so that we could advise someone whom we know to be competent.
