>>81881610 (OP)psych ward is not comfortable
"good" psych wards will let you use your phone but won't let you leave early. They'll fight you if you try to sign a 3 day and leave in 3 days. The one I went to seriously tried to push ECT and again when it didn't work. Because they would't let me leave without "fixing" the problem.
Ironically, shittier psych wards are easier because they won't want to fight a 3 day. But you can't use your phone. If their book selection is trash, you can get someone outside to donate books from a thrift store like goodwill or salvation army
