You're not the first person to be in this position, and there are ways out. My advice is to find something that pitches a career change to organisations. For example, take a short period of study, and then in your applications say something like "After 10 years of X, I decided to follow my real passion Y, and I'm now looking for ways to expand in this role. Of course, I still bring all my past experience that I believe will be invaluable in this junior role..." I've seen people do this - it works. Tell a story, believe it yourself, and you will convince others to give you a chance in a junior role that you can them move quickly upwards from.
