Does anyone know of any Inpatient psychiatric care centers and/or therapy resources for those without insurance?

I have searched the sub but all I could find was pre-covid and years old recommendations and I’m just overwhelmed. I think there used to be inpatient near Ben Taub? Is it affordable? Can I voluntarily leave? Can this effect custody arrangements? My children are safe and in good care. I don’t want them to see me suffering and we live with my parents so a stable adult is always present. I’m also in my senior year and I can’t fail this semester and need to be back within a week max but have been struggling for a long time, but have been functional and hide it well. However I have become alarmed with the extent that my mental health has began increasingly deteriorating over the past week. Thank you endlessly for any advice.
