I went inpatient for 10 days during christmas for SI intent....I'm still depressed

earlier this month I went hypomanic, then normal all in a 4 day span.

Now I'm just depressed, constantly thinking about suicide.

googling how to kill myself.

But I know I'm not gonna kill myself this time.

I'm crying, constant headaches.

I'm bipolar but I never stay on the up-side of the spectrum.

Since I'm not going to hurt myself or anyone else should be I going to an inpatient psych ward?
