Is there any difference between "I'm planning" and "I'm planning up" when responding to a question about hypothetical plans? Where does this "up" come from?
The context is a conversation between two persons. One of them says that he is "planning up" to begin something in the future, just like "Yes, I'm planning up.". But I assume that he could just say "Yes, I'm planning" and this would have identical meaning.
Update #1: This phrase is from Ozark series:
Now, be honest. When was the last time you were really truly happy?
Come on. I'm planning up.
Here is a screenshot of the dialogue from the series.
