Hi Adrianna, this calathea plant is a bit dramatic, but don't worry, you can still take care of it. Let's take a look at what might be causing this behavior. Is it possible that it's just a little too much water? Do you think there might be any rotting roots? I'd suggest looking at the roots and gently moving them to a new pot with fresh planting mix. Humidity may also have an impact. You can use the best soil mix, like one part peat moss (or, as a sustainable alternative, coconut coir), one part perlite, and one part vermiculite.
