Self harming

[PurpleLion2]

My DD has self harmed on and off for about 3 years now, she's only 15. She has recently been feeling low and has told me she worries she's going to cut again after being clean for 2 months but doesn't want to. A positive step I thought. I have been in
Touch with the school she has a lot of support. She's on the list again for counselling. I have been in touch with the gp, she had an appointment with the mental health nurse last week that gave her some fabulous information to go forward with.
Today I have found 2 tools she would use for cutting in her drawer next to her bed. I regularly check her room- she doesn't know. Do I tell her I have found these and have it out with her knowing she will be angry I've looked in her drawers?
Or do I not says anything and leave it there but continue with the support and hope she makes her own decision not to cut.
Or do I take it away and not say anything and see if she comes to me (probably angry) when she realises they are gone?
Help please...

Hello. I am totally new to this and DD (been doing self harming for a year apparently) has said she is not ready to stop so I am imaging the worst. All the advice I have seen says that you shouldn’t stop them and shouldn’t confiscate sharps. It is so hard when you just want to protect them.

You are her parent so you want to protect her
But you know she will just find something else if you take them
So I think you need a new approach
Remain supportive obviously
But you may find she wants nothing to do with you when she realises you've gone through her stuff
