well done on your first day!! i began volunteer work some years ago when i was unemployed and depressed. I was scared too but i found it great! The people were so kind (volunteers are usually very giving, this includes you ) Your confidence WILL go up as time goes by, and try not to worry about the customers or any other strangers u meet...they probably won't even notice your anxiety. Good luck with this and i hope u enjoy yourself!!! You're out there, and your giving back to the community..wonderful!
