Thanks for your post, Darwinia. I'm sorry I have only just picked this up, the links are really useful, and may well explain why things worsened with the onset of exams. And have again with the worsening of covid restrictions.
It's good to hear from someone who has first hand experience of what my daughter is going through, particularly as her teachers and CAMHS counsellor don't quite get it. The article on Moral Scrupulosity describes her so well, and will hopefully give her some help in communicating her fears over accidental plagiarism (and yes, she is the last person who will ever plagiarise !!).
I think it will help for us to also formulate together a 'mental health first aid' plan for when things get tough - there may well be no exams now this summer, but there will be other stressors, no doubt.
Thanks again ?
