You're either thinking of some other account or you had local data that you haven't synced. Your online library with 88 items has never had other items in it. Nothing has ever been deleted.
Can you tell me when this current email address was established? My belief is that I set up Zotero in 2017, and iteratively added to it, on two separate computers.
I'd follow the advice on email addresses: You can see on https://www.zotero.org/settings/email which emails are associated with the account your posting from. Then try password reset to any other ones you'd plausibly have used.
The only thing that changed is that I downloaded a new version of Zotero when I bought my new computer in January. Is it possible there is some glitch?

And I don't think there was local data that was unsynced, since I used to access it on different computers.
You can try resetting your password with other email addresses you have.
But you'll need to trust us that there has never been any other data in this account.

is it possible that I missed an email, saying that my account would be deleted? And I then did not realise I was only saving locally?
But there is a problem, because my 88 items do not include those i saved previously??
I have used Zotero for many years, on multiple devices, but cannot see prior content. Can you please help.

If you can't find it, email support@zotero.org and we can tell you the account name and address.
