Windows 10: User account disappeared from laptop

I went to log on to my user account on my laptop after not going on it for several months, however I had forgotten my pin. I clicked on forgotten my pin expecting there to be an option to change it or something but instead my account has now completely disappeared from the laptop, leaving only my daughter's. My account was the main one meaning that I was able to authorise things such as changing settings etc so I am now unable to make a new account unless I'm missing something and have no idea how to recover it. Is anyone able to help me please? I'm not very good with things like this, thank

:)

To delete an account, follow these steps:

1. Press WIN + X keys and click Command Prompt (Admin) from the menu.
2. Type the following command and press Enter. Replace test with the name of your sister's account. Code:
