I'm pretty much in your same boat, I had my nose broken as well and it's slightly curved to the side with almost the same bump. I know exactly how much you notice it every time you look in the mirror, and wonder why people don't just stare...
But, then I look at your picture and until I studied it I didn't even notice your nose. I see your chin and while today it is slightly squared I believe it will round off.
I am going to side with those and say give it time. I want to throw my picture up here right now and say ok girls, tear me apart what do I need? But then I realize that this is a process of 12-18 months, and I'm cheating myself if I go for anything now.
Two things that I'll say you will need regardless is a trach shave and your nose fixed. Other then that you have an amazing base that I think the hormones will take care of for you. And gain some weight! I am also like you and really skinny, for me it's extremely hard to put on weight be it fat or muscle, but find some way if you can and gain weight and I'm sure that will help a ton as well.
You are beautiful, so wait at least a year before deciding to do anything.
