Been in wards/behavioral health hospitals about 5 times in the last 2 years, every time was a horrible experience. Being in those places gave me nothing to think about my attempts and feel worse about myself and life. You have no freedom, you wake up when they say wake up, you eat when they say eat, you sleep when they say sleep. I remember not being able to sleep at night as I worked a night shift job before going in to some of the stays and at some facilities I wasn't allowed to catch up on sleep during the day. If you're not hungry during meal time, too bad because you wont get another chance to eat until next meal. I remember stuffing down food when I got the chance to avoid starving between the meals. I'm about 125 lbs, very skinny and I don't have much appetite, but I still found myself frequently hungry. You can be surrounded by unpleasant people as well, my last stay I had an woman much older than me walk into my room at night, frequently and made the mistake of letting some of the other patients know that I didn't believe in god, leading to many conversations about religion and straight up conspiracy theories that I wasn't interested in. On another stay one of the patients would refuse to sleep at night and screamed into the halls every night. One of the conditions I agreed to when I signed in (involuntary commit) was the right to refuse medication, which the doctors revoked, when I asked not to take anxiety medication they gave me. I was told that if I didn't take the pill they would hold me down and inject me, and that I would be reported to the doctor for non compliance, extending my stay.
I'm going to stop now, because my list of bad experiences goes on and on, but if you have any questions feel free to ask me. I would advise against going to a psych ward or behavioral hospital unless you feel incapable of preventing yourself from harming yourself or doing something you'd regret. And if you do go, commit yourself, as if you sign yourself in you can request to be discharged after 48 hours after you ask. I seriously think that my time in those places had a significantly negative effect on my mental health overall, and I never gained any benefit from going.
