Going home, not okay

So, they have sent us home. This isn’t even legal or ethical. They just waited until the nurse who had talked to me earlier left, and then an ER doctor came in and basically said they were sending me home. Going to need all the support I can get. My case worker told me the other day that if I go to the hospital where they don’t think it is an emergency then my case worker will terminate services with them. Don’t know what I’m supposed to do. They only made like a two-sentence safety plan.
