My DD is very timid and shy. The high school students used to bully her often. She is not poor in her studies and used to come up with average score in exams. But weak in expressing her ideas. She often breaks down while teachers ask her academics related questions. She always hated high school. On their prom party some of her classmates threw trashes on her and made fun of . She was completely shattered after that. Now is going through a mental trauma. When I spoke to the psychologist he told a private online education would be better for her at the moment. How can I build back her confidence? Any advice?
