This is classic overwatering. Notice how the leaves are ribbed making them look puffy, that’s from being water logged. It forces the leaves to curl down like that. if it was under watered the leaf stems would droop as well and notice how these stems are pointing up while leaf curls down. Do everything you can to dry her out as quickly as possible. Give more heat, better air circulation, lower humidity, carefully poke air holes in soil or just sit the plant outside of its pot. Resume watering only when completely dry, at half the previous rate and add oxygen to your water with air stone. 🍻

Looks like she is suffocating from overwatering
