French false friends are ruining my progress—any tips?

I am a heritage learner trying to reconnect with my family roots, but my background in French is actually hurting my Haitian Creole. I keep mixing up 'false friends' and using French syntax instead of Creole. How do I 'unlearn' the French reflexes to sound more natural when I’m talking to my aunties? I don't want to sound like I’m just speaking broken French.
