<human>: At the age of 18 I had a breakdown centred around exam stress. 5 years later and now fully recovered my SO and I are both studying to become teachers. Within our course we studied a parenting technique that my parents use and which I believe explains why I suffered with such deep anxiety over exams that I had a breakdown. At the time I decided that it would deeply hurt my mother to find out that a parenting technique that she used in good faith (and FYI is in no way abusive) and is an accepted, and even praised and popular, parenting technique had contributed to my breakdown and decided that I would not mention it to her.

Fast forward to now, my youngest sister is has just started college and I went to visit her. She told me that already in the first week of college she was experiencing anxiety around exams that will not take place for months. She also had such bad anxiety about her exams at the end of high school that she started plucking out her own eyebrows and eyelashes. I recommended that she visit her school's counselling service and explained to her a little about the educational/parenting theory that I had read about and sent her some information about it that I thought might help her. I also called my mother and told her that I had suggested to my sister that she might benefit from counselling/therapy, to which she responded that the problem was just that my sister's revision techniques are bad!

My parents are in general fantastic and loving but they have some deeply ingrained beliefs about education and parenting that I believe are damaging myself and my sister. I think that it will really deeply upset them to hear this. If they take this seriously it will knock them sideways as they will realise that they have - through no fault of their own - damaged the people they care about the most. So my question is, should I let sleeping dogs lie and work with my sister behind my parents' backs to improve her mindset or should I bring it up to my parents and risk deeply hurting them?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Is it necessary to tell my wonderful, loving parents that I believe their parenting technique is damaging my sister even though I think that it will hurt them deeply.
