How do you face your fears?
There are two aspects to dealing with fears. The first one is the medical aspect. Some people suffer from anxiety disorder which makes them much more fearful of things and situations than is normal. Such people will greatly benefit from medical help since there are many effective drugs that can strongly reduce anxiety and help such people lead a normal life.
The other aspect is the spiritual aspect. The closer you feel to God the easier it becomes to face your fears. By fully relying on God and keeping His remembrance alive in your heart constantly you will feel as if nothing can harm you unless God wants it, so you will feel much braver in facing your fears.
