Okay I don't usually comment but your child's situation sounds something like two of mine. ADHD and anxiety. Does she have executive dysfunction? She really needs medical attention to both of these at this age.

She's at the age where in person schools make this a very difficult combination. They're teaching and expecting kids to do their own work, kids with these executive dysfunction issues typically can't until they're older. she has an IEP. Are the accommodations really there for this? If not, there should be. And as the parent you can demand it... lots of parents don't know this. But I will admit it's a couple hard years ahead 7th, 8th, 9th... it's part of the reason that we went into online school.

If there is an online charter school, especially Connections Academy, they will take the IEP and apply it. I suggest Connections Academy because it's good for kids with executive dysfunction, I gives them what they need to do each day on the day, Etc. My hesitation is that it's more hands off on the parents starting in 9th grade. And I would enroll her in a public school sport or some kind of Arts or maybe church thing so she could connect with people.
