Social anxiety so severe i have missed job interviews over it and have a panicked feeling even going to the grocery store. no insurance. what can i do?

Many Options: Most cities have clinics or health depts. That provide free or low-cost or income-based payments medical/mental health services. Many accept care credit or other similar financing. These companies lend money for medical purposes & accept a higher risk since most people pay for medical care before they pay other bills. Doctors are not banks & do their best work when they are not being bankers!
