I've been looking into this and seen multiple forum threads of people delegated access by ex's, relatives who have passed away and the like who are unable to remove themselves from this access even if it's extremely painful.
It blows my mind that this isn't a feature that exists or that Google can't help you remove your _own_ delegated access.
Anyone encountered this before and found a solution?

Otherwise, it might be a forward.
In that case, the only option is to add a filter -- if email is marked TO:themail@domain.com, then mark as read, delete, not marked as important.
Once you've been delegated access to a Gmail account, it appears in the list of accounts you can switch to, but only within the Gmail web UI.
When you explicitly switch to that account, you see the other person's mailbox. If you never click on the switcher, you wouldn't even remember you had access.
Given the above:
- filtering makes no sense, because the mail items never appear in the same mailbox anyway
- changing password makes no sense, as you can only access gmail and not the whole Google account
Painful memories should be avoided this way
