I did everything they asked me to. But they were never all their lives happy at anything.
Remember this as you consider what to do. So...it would seem that getting them to name lists of things to do and you doing it is unlikely to result in their happiness.
Since you have moved out, can you share how you have tried to communicate with your parents about this issue. If you can pick an representative incident and give us as much detail as possible "you said"..."they said"...it would likely help us provide ideas on how you can turn the temperature down in your interactions.
I can't imagine anything good coming from interactions where they are threatening to destroy stuff...so...it would seem step 1 is to "turn down the temp."
Best,
