I think that a gap year is a very good idea for you. I also think it would be very beneficial for you to work with with a professional counselor and, among other things, learn some coping mechanisms for when you’re going through periods of great indecisiveness and anxiety.
Perhaps after working with a counselor you will decide that Davidson is the right path, or maybe you will decide to apply to different schools for SY23-24, or maybe you will decide on an entirely different plan. But I think you need more assistance than the CC community can provide.
