Your situation is a little unclear, but presuming this is a "Legal 2000" hold, you girlfriend was presenting as a danger to herself or others, and will be held for 48 for observation and, if necessary, treatment. What you can "do" is get her appropriate follow-up treatment once she is released. Given the pandemic, many mental health practitioners and programs are available by "telehealth" remote work. Find and use one; many are very low-cost, or even free.
