How can I break my nose so I can get reconstructive nose surgery?

Don't do it. That is dangerous & could affect your breathing, cause infection, or severe bleeding. Besides, the surgeon will reconstruct your nose back to the way it was. You probably want a rhinoplasty in which the shape of your nose is changed. You won't get that result via reconstructive surgery. They could change the shape but your insurance won't pay that. See a psychiatrist first.
