Admitting Myself to a Psychiatric Hospital: What to Expect?

If you are in the US, you can qualify for leave through FMLA. Legally can’t be fired or demoted for that. You need a doctor to fill your paperwork for that- a psychiatrist can do so as well. They don’t even need to specifically name the condition or nature of the condition if you don’t want to.

Talk to someone at work, mental health is included in short term and long-term disability/leave/paid time off and no, legally they can't just fire you for asking for time off for mental health concerns. In fact, it's pretty common in most industries, just not discussed. Inpatient care was a huge step for getting stable for me, I wish I'd admitted myself instead of waiting until I to the point of being suicidal. It'd have saved me a few years of suffering.
