I'm very shy and quiet, I'm currently 29 and back at university retraining and I can't answer any questions in class even when I know the answer. Same with work meetings, I just can't speak up. I'm drained and exhausted from everyday life and have considered if I'm autistic or have inattentive ADHD. I burnt out in jobs, always have poor attendance as I struggle to keep up with everything
I found my school reports from reception onwards and every single one says I'm too quiet, too shy, need to join in with class discussions. My report at age 4 could have easily have been written about me today by a manager, just replace 'doesn't join in with class discussions' with 'doesn't join in with discussions during meetings'.
Surely if it traces back to age 4 it isn't CPTSD or social anxiety?
