If you seriously can only see yourself doing mathematics or physics and define your self-worth by your accomplishments in these fields, then I strongly recommend you to get professional help from a psychologist who can help you to work with other self-values. It may also help to have a contact with a psychiatrist as you may be very likely to develop depression if you have not already. It is not healthy to obsess over two of the arguably most difficult carreer paths you can select. I have seen first hand what this can do to people and it is not something to strive for. I also have many friends who did PhDs in mathematics and physics who went on to industry and have highly interesting jobs where they can use their expertise. Do not paint yourself into a corner.
