Will my toenail ever be smooth again after my injury?

So a couple weeks ago, my brother had a birthday party with a inflatable. When i jumped off i hit my right foot heel on my left big toe. It hurt like crazy. It was bruised and turned purple after a few hours. I waited till the swelling went down so i could walk properly again. That night when i was laying in bed, i checked if my toenail was okay, and it started falling off. Now, the whole nail is about to fall off. Will it grow back? And look as normal as it will back then? Im really disappointed. And my mom is a nailest and told me that my toenail will never look nice again because of this :((
