Bipolar here. Also have been admitted into the hospital a few times. Yup, it's straight babysitting adults but it doesn't always have to be aweful. First, go to the ER and ask to be checked into the psych ward voluntarily. By doing so (if you're in the US) you can check yourself out, which gives you some power. Then check in. They'll take your laces and your phone (and the USB-C cable) and the food is terrible and art therapy sucks, but they'll take care of you and give you a much needed rest and a reset. Yes, you'll have to take the meds they prescribe and it's not always great, but it'll work. You'll get sleep, you'll get time.
I went through a VERY bad period in my life. I had Bipolar Disorder 1, Dissociative Amnesia, and Persistent Complex Bereavement Disorder. The last one was the worst and it lasted forever. 20 years to be exact. It was excruciating. I tried several times to commit suicide. They kept telling me over and over that eventually it would get better. I was out of hope, I didn't believe them. But in a true miracle from God, it actually happened. I'm not very religious. The evangelicals sent several people to my house telling me how it was my fault, it was my sin, satan was behind my bipolar disorder, I needed to stop my meds and just pray and it'd all go away. They were wrong. I needed meds and therapy. I had terrible doctors that threw med changes 3 at a time until they were confused as to why I felt the way I did.
Sometimes Mental Health diagnosis and medication therapy (and therapy-therapy) take a very long time. It took me 4 doctors and 5 years before I started to feel that the meds were taking the edge off. And about 10 years until I felt good. I feel amazing. Every night I pray (in my own little private way) that God finally helped me. And I thank him for that.
Sometimes we get too involved with religion (I'm going to get some downvotes for this) but some people will tell you that prayer is all you need. It's just not. Sometimes you need to talk it out, sometimes you just need a med change/check. Idk if this helps, but be deliberate. Think things through. Get help at a medically sound place. Yea, it sucks that they take your shoes and laces, but the grippy socks sort of rule and taking a break is kind of breathtaking. :)
