How to deal with a family member with depression and anxiety attacks and doesn't take medication?

Before you move the person to doctor, if you happen to see that the person has an anxiety attack, try to relax the person. If there are many people around, disperse. Talk to the person in simple way. Do not complicate things with any reasoning. Try to relax him by being supportive and being there. Say things that are motivational, and help in lifting his self worth.
