Your honesty and transparency are honorable. While it's difficult for many people to admit mistakes, it's important to do so, and doing so not only reveals that we are good people, but also that we can improve / become better people.

I'm not sure of what you should do, but one thing you can do is make sure that any and all earnings from those accounts are used ONLY to SUPPORT OTHER Steemians.

Best of luck. Stay honest and Stay Good.
