There have been huge advances in the way neuroscience understands the relationship between mind and body. There is now a plethora of people offering all kinds of help and it can be difficult to sort out the genuine ones. I would recommend finding a doctor who is up to date with current thinking and not one of the many who are opposed to it. I am fortunate in that the local National Health Service is on board and they do try to offer appropriate psychological treatment based on individual experience. They actually recommended that I listened to Gabor Mate and I would recommend him for starters. Following his teaching you might even be able to sort it out yourself.
