Hidden habits that make your social anxiety worse - and how to break them

It was during her teenage years that Mary began to become anxious in social situations. It got so bad she developed depression and had to have time off school.

"I didn't join clubs and societies like others did," says Mary (not her real name). "I just thought nobody would want to get to know me. I didn't really make a single friend during my whole degree."

Mary's social anxiety was so bad that she was diagnosed as having social anxiety disorder - something that affects up to 12% of people , external at some point in their lives.
