First thing you should do is take a deep breath in and out to collect yourself.
Let me give you some advice as I've been in a mental hospital before, and I've had to appeal my way out with the doctors and nurses. The best thing you can do is create a reasonable argument. Articulate yourself well, and ensure that you make practical sense. The doctors are used to patients being unreasonable, making incomprehensible demands or expressing "unapproved" thoughts. If you can speak with authority, not to imply dominion over the staff but in dominion over the self, then they'll be inclined to release you.
That's pretty much what I did, and the nurse interviewing me told me "you have to be the most sane person to come through here." Which I found to be hilarious as I was admitted in due to a panic attack leading into a mental breakdown.
Keep your cool, make a valid argument, and hope for the best. I'm rooting for you anon
