They usually stay around 10 days. Though the last time they went, they went to a different psych ward and was there for 22 days.
No, I have no idea what psych ward, or hospital they went to. I have no ability to just call the nearby ones in their area to try to locate them.
No, again. My friend has a cousin who lives nearby, but I have never had their phone number.
So, yeah. I have no way of knowing anything, unless my friend contacts me.
I could have up to 2 more weeks until I might hear from them. That is, if they went in last Tuesday. Like I am hoping happened.
If only I knew if they made it to a psych ward or not, would save me a lot of worry. As it is now, I am a mess, and only getting worse.
