Have you tried offering her pellets? Something different and, even if she only eats a little, at least it's 100% nutritionally balanced. Sunflower seeds are like candy or caffeine for birds - it can lead to aggression, biting, screaming, and plucking to eat too much. If she's not eating a lot, until she balances out, make sure to just give her whatever she'll eat.
Personally? I would take her to the vet to make sure there's nothing medically wrong with her. From there, I would just keep offering lots of fresh goodies and maybe 2-3 sunflower seeds a day. The fresh goodies (fruits, veggies, grains, pasta, etc) are very nutritious for her. I have heard of people putting their birds on an almost completely fresh diet, so... it's not the worst thing in the world for her.
Check her poops - are they consistent, green (or discolored by the food she's eating), and solid? Are they a normal size? If they're consistently black, or very very dark, then she's burning her fat stores and should really go to a vet.
Also check her weight, if she'll let you handle her, and keep feeling her breastbone to make sure she's not lost too much weight. A bird can lose 10% of it's body weight before it hits a critical stage and needs a vet visit ASAP.
One last thing to check (sorry, I know this is a lot!) is her water intake - is she drinking enough water?
