Formal:
* Mwen manke ou anpil. (This is the most literal translation and is appropriate for formal situations.)
Informal:
* Mwen anvi w anpil. (This is a more common way to say it and conveys a stronger sense of longing.)
* Mwen santi mwen manke ou anpil. (This is a slightly more emotional way to say it.)
* Ou manke mwen anpil. (This puts the emphasis on the person being missed.)
More casual:
* Mwen renmen ou anpil, mwen manke ou. (This combines "I love you" with "I miss you.")
* Ou nan tèt mwen tout tan. (This means "You're always on my mind" and conveys a strong sense of longing.)
It's important to note that Creole is a diverse language with many regional variations. The best way to learn how to say "I miss you so much" in Creole is to consult with a native speaker or learn from resources specific to the dialect you're interested in.
