Linked e-mail id’s found un-linked

I have more than one e-mail accounts which were linked to my main id. But now when i click "my picture" icon on the top extreme right corner the earlier-linked accounts are not available. Pl. can somebody let me know what happened to the those linked accounts? I forgot the log-in id's and the passwords for the same too since I was always using the main id to enter the other id's.
