Poor latching

She never opens wide enough for me. I try ten plus times and get no more nipple in her mouth. I want to scream. I've seen two LCs and watched numerous YouTube videos but no improvement. I'm getting so stressed and upset at each feeding. Not to mention the nipple soreness. I'm using a nipple shield on the right but that's not ideal either. I'm out of options and feeling like we'll never get better at this. She's 4 weeks today. I know she's getting stressed too which doesn't help. Just feeling hopeless despite my healthy growing baby.
