I don't believe telling others for you to heal is dishonoring your parents - you're doing it for your healing - it's not even against them in that regard. I also don't believe God would expect you to not report something if you saw abuse (or any crime).
One thing I do want to say is do not over-stress this, if you can. We are flesh and blood, human, and we make mistakes. Fortunately for us God looks at the heart - the intentions - the desires and tells us where we fall short - His grace is enough to cover it all. So even if you don't get the honor thing "perfect" - it's ok. Remember God's grace, and claim it's promise.
And breathe. Remember to breathe.
