Will it ever get better?

My baby is almost 6 weeks old and am efb her. She had a small tongue tie that got clipped last Thursday. I have been trying to do some suck training exercises but it doesn't seem to be helping. I have tried to use a shield but she doesn't get enough when using it because of her latch. I would pump but she doesn't like being put down longer than like 10 minutes. Any advice on what to do next? Anyone experience something similar? I'm hoping for a miracle or at least some words of encouragement that it will get better!
