DD16 has been pretty confident up to recently when she has started to doubt herself and massively overthinks everything. It's mainly related to her friendship group where she is constantly worrying about what they think for example if she says no to going out with them and if she does go out with them she worries about what she might have said that could have upset them. I don't get the feeling they are actually being mean it seems like mostly it is just DDs own insecurities. She is constantly questioning and overthinking and it is becoming a problem. Has anyone else had experience of this and have any ideas how I can help her. TIA
