I do think that if there is no one available to help you outpatient that a stay in the hospital would be a good option. Since (as far as I can tell) you are not considering sui and don't have plans to harm anyone else, it would most likely be a short stay; just long enough to help you get some good sleep. Of course I'm not a doctor so I can't speak for them, but that has been my experience. Staying in the hospital is not exactly fun, but becoming psychotic from not sleeping would be much, much worse since you'd end up in the hospital anyways, and probably for a longer stay. Take care and I hope that someone can help you!
