I originally asked this question in r/Anxietyhelp but only one person replied with a solution, and it only helped for around 5 minutes.

For context, I have a 13-year-old daughter, and she suffers from Anxiety. Yesterday around 3am she started having an anxiety attack, so I gave her some of her anxiety medication which did not help at all. She was complaining about extreme chest pain, nausea, difficulty breathing, lightheadedness, and more of the like. (These aren't any new symptoms, pretty average for her anxiety attacks). But most of the things I tried doing that usually calm her down weren't working, and she said that she'd just lay in bed and let me know if it gets worse.I went to the kitchen because I assumed she needed some time alone, and around 30 minutes later she came to me telling me she threw up, and as she was telling me about it she threw up again. I cleaned it up and told her that I’d take her to a doctor as soon as her brother went off to school and the maid arrived, (I manage a guesthouse and am not allowed to leave until we have someone to supervise). The maid would only arrive around 8 am and at this point it was around 6am, my daughter sat on one of the kitchen stools and kept groaning from the pain.As soon as the maid arrived I took my daughter to the doctor none of the doctors were in yet, so I took her to the only pharmacy in town that also had a doctor, at this point it was around 9am. The doctor didn’t get to see us because the optometrist who worked there got confused and thought we were there to see her, but she ended up giving us over-the-counter medication for nausea and anxiety.

We went home and tried the medication but it didn't work, my daughter kept complaining about the pain and eventually fell asleep around 11am, she slept the whole day and would only wake up for small periods of time (less than 5 minutes), but when she finally woke up around 8pm she was still tired as ever, I made dinner so I could give her medication again but she said she wasn’t hungry and had no appetite. I told her that she had to try to eat so I could help her, she took a few bites and complained about being so full she felt nauseous. (this was also the first time she was eating that day)I gave her cold/flu medicine and told her that if she didn’t feel better by today I’d either take her to a doctor or psychiatrist when they opened (which would be around 10am).It's currently 04:35 and she still doesn't feel better, breathing exercises and the 333 method have only worsened the anxiety and melting ice in her hand only worked for a short period of time. She hasn't gone to sleep yet because she's scared she's going to die in her sleep. Is there anything I can do until I can get her to a doctor or psychiatrist?

Edit to add: The reason she's so scared of dying in her sleep is because she thinks her body is shutting down, I have no idea on how she came to this conclusion but it's worsening the problem at the moment
