from what you've been writing lately ... every other source of help you've tried hasn't been able to provide you with the care and support you need (other than the most recent person who you were still waiting on)

... and you've also mentioned being a danger to yourself; so yes ... i think for right now it's the best option you could take --- a scary one, but also a brave one in you going in now, and i hope that bravery pays off by them being able to help
