@Colin_T Do you know what your login details are for your email?
Was it through your internet provider or is it a generic one like Google or Outlook?
I can probably walk you through setting email up on your phone but if you are likely going to lose access to your current emails soon then we need to sort that first, especially if you use it for anything like banking/shopping, etc.
If you are going to lose access to your email (i.e. its through your internet provider) then you need to get a new one set up and make sure you update any online accounts you have with the new email address. This needs to be done before you lose access to your email because you will probably have to use that email to verify changes.
I'm happy to try and walk you through all of this and help set up a new email account if you need it.
