I've been in the hospital twice. I agree it is bad to not be able to leave, but if you go in voluntarily you can leave. You just have to go thru their PITA steps. They are just trying to keep you safe.

One advantage of going was that I was able to be tested for mental illnesses while I was there. Another is that I learned a lot about trauma and responses to trauma. Another is that I was safe. And I got the week off from stressful and triggering things.

They probably will mess your meds, which can be a good thing or a bad thing. Most meds for mental illness are a guessing game; they work differently on different individuals.

In the hospital I was in, you could talk to an aide or a nurse if you were up in the middle of the night. They made us get up early but didn't have a set bedtime. You can also request sleeping pills when you see the dr.
