Hi, welcome to RYL.
It's great that you want to help, and I hope you find RYL useful for answering your questions. Feel free to ask anything if you need to, but the most important thing is just letting your daughter know you're there for her (which it sounds like you've done).
You might find the
information for parents helpful, else making a thread in the Self Injury board or General Support and Advice board.
You and your daughter are also more than welcome to contact the Supporters (support@recoveryourlife.com) if you need to talk.
Take care.
