Toe - Understand your frustration but you can't just "sign yourself in" without a need. I'm not familiar with your area but if it's similar to mine you should visit the county hospitals ER and they will make an asessment. Normally they have what's called a crisis team that will evaluate you. If your need is emergent you will be seen right away and helped. If you refuse the help offered by way of medication you may be SOL. There are only so many alternatives for drug therapy.
Being on Medicaid has nothing to do with what you need. Your county facility will take you Medicaid or not and help you but you have to be willing to participate.
