Hi Scott. I presume you mean England UK? Here choosing to go inpatient does not mean that will happen unless you have access to private health care. Inpatient mental health care on the NHS is becoming more and more scarce, and is unlikely to be available where and when you want it at will.
If you have a therapist, speak with them, if not go and chat with your GP about what your options, in your area might be. If you are desperate, then present at A & E or call a crisis line such as the Samaritans.
Let us know how you get on
Regards
Lucy
