How would you react?
My mum found out when I was 14/15. I was doing the washing up, she spotted a mark on my arm and grabbed it, yanked up the sleeve and saw more shallow cuts.
I remember her screaming angrily at me over and over "why are you doing this to me?!". Lots of crying (her). She called my dad (separated for years), couldn't get through so called his brother & wife (aunt and uncle). Not a clue why, I only saw them twice a year, so I can only think she did it to punish me by sharing what a "naughty ungrateful girl" I'd been.
No counselling was sought or suggested. No trip to the GP. Just a very stern warning that I was never to do it again and why would I do that to her after she "bent over backwards for me".
I don't think that was normal, was it? I had a lot of MH problems in my late teens, threw myself into the first (awful, coersive) relationship that came along, kicked out at 16, and still have self-esteem issues. She talks about how my brother and I had everything as kids but I don't remember it being like that.
