I had a toenail injury. The doctor told me that the nail will have to be removed. I am hesitant. Please help.

Hi doctor,

I have a question here. I had a toenail injury last month (cause: fell down, toe landing first onto the floor, which made the nail get loosened). I did go to the hospital to get it treated. The doctor cut off half of my nail, cleaned and dressed it, and kept re-visiting to get the dressing changed. The doctor said that I could stop re-visiting. And then she told me that the nail would have to be removed again after it grows back fully. But, I am hesitant and kind of rejecting to do so.

After a month, the nail is not loose anymore, but the nail seems to be growing outwards, and between the nail and the nail bed, there is a gap (kind of like a hollow gap inside). Should I just wait until the nail fully grows back? Should I cut it? What should I do? I am really worried that it will not grow and it will completely fall off once I start wearing shoes. Please note: I am going on a horse riding and hiking camp the next month. Just in case if it does not grow back by then, what should I do or wear to protect it?
