Some things come and go, for me SI-ing was a huge thing at that age for me, and started to fade. I'm not saying people can easily get over it, but it's possible. Just be there for your daughter. Just don't pressure. Being someone that SI themself, and being confronted or having sertain people know you did is a really weird and awkward feeling. It takes time though. Just try your best to watch out of some warning signs. Keep in touch and good luck, let me know how everything goes.
