No one should have to endure such agony and pain. I would suggest as a last resort since there are no free clinics in Arizona and if you can't afford a doctor visit to go to ED. They can not refuse you for no insurance in ED. Tell them you are suffering from depression, anxiety and severe headaches. They may actually admit you inpatient to further evaluate you or if not subscribe some meds. But do not go alone. Go with a family member.
