Yes is the short answer, but, like all therapies, it will depend on how much you want to change and how well you engage with the process.
I have been uncomfortable around birds my whole life. When I was training as a BWRT level 1 practitioner, I worked with a fellow student who helped me overcome my fear in just one session. I felt comfortable and relaxed in situations I would previously have avoided and didn’t even notice what I would previously have thought of as a threat. My husband pointed that out to me as I sat in Trafalgar Square eating a sandwich!
Since qualifying I have helped many clients overcome their fears and phobias, live with their guilty secrets, become reconciled to a relationship breakdown or a difficult childhood and even change how they think about themselves.
