Omnia parentibus meis dicam/dictitabo
Here you have a translation:
-Parentibus meis: Dative, "to my parents" (this includes mother and father)
-dicam/dictitabo: both mean "I will tell", future tense; though, the first one is neutral and the second one gives a sense of tell something that shouldn't be said, like gossip etc. which could fit your context.
Hope it helps!
