@raspberrytorte, I learned a technique for dealing with a crisis situation:

Put your daughter's face in cold water, or use a Ziploc bag full of cold water and hold it over her eyes and cheeks. After 15-30 secs this invokes the body's dive response that causes the heart to slow down and blood flow is redirected to the brain.

This is a distress tolerance strategy that I learned when having very strong, distressing emotions or when having very strong urges to engage in dangerous behaviors.

Talk with your daughter about the consequences of her decisions, are they making things worse?

Use a skill called STOP...

S - Don't react. Stop! Freeze! Your emotions may try to make you act without thinking.

T - take a step back from the situation. Take a deep breath.

O - observe. Notice what's going on inside and outside.

P - proceed mindfully. Act with awareness, consider thoughts and feelings and other people's thoughts and feelings. Which actions will make it better or worse?

These are crisis management techniques that can help lower the level of crisis from a 10/10 to maybe a 7/10 which can make a big difference in the moment.
