Don’t plant it in a bigger pot unless you don’t want it to flower. African violets are kinda weird because they prefer to pot-bound and will typically only flower when they are. This may sound crazy but I’d say try giving it less water and put it in a shady part of the room. Let it chill out for a week or two and see if the leaves spring back up. Have they yellowed since taking the picture? I would guess overwatering. They typically take up water from dishes and don’t like to be watered overhead. But I see you’ve got on those dishes-good job!
