Doubtful trauma created anatomic change in the nose.
I don't see a great deal of difference between the pre-and post trauma pictures. Is highly unlikely that your nose is broken to the point where the trauma would have made an anatomic change.
My nose looks different after getting hit 4 months ago and my glasses don't fit right, what happened?
Best to be seen by boarded surgeon with a parent. Than you can determine exactly what happened and when and what can be done to improve the issue..
