Please visit an ENT specialist for a proper physical evaluation. You could be suffering from a condition that causes nasal obstruction, like, Nasal Polyposis (commonly due to nasal allergies), Deviated Nasal Septum, Chronic Rhino-Sinusitis or Hypertrophied Adenoids (not usually seen at your age). Appropriate therapy, based on the cause of your nasal obstruction, would be beneficial.
