I had this with my 13 year old daughter, I had the benefit at the time that the therapist I was seeing for myself has decades of dealing with young people who self harm.
we managed to turn it round within a few weeks and have to say it’s almost been the making of my daughter, she’s much like me in that she puts a brace face on but when I found out she was harming herself it was a wake up call to take more notice that she needed more support than than I thought, she’s now soo much more confident, happy, open, affectionate.
things that I think helped..
don’t focus on the act of harming, focus on the feelings behind it
at all costs avoid any shame or panic about the act of harming, sounds like you’ve nailed this already with your response to her telling you ❤️
most of the time it’s a control or relief mechanism for them, work hard on giving them autonomy in their life and helping them recognise that they have a choice and a voice in pretty much everything in their lives. Have a good honest look at any controlling or overbearing parenting you might do too
speak very openly and calmly about the things you will have to do to keep them safe such as taking sharps away, emphasis that this isn’t because your done trust them but that it’s because you love them and want them to be safe from harm
teach them how to love themselves and lead by example
if they need MH days off school give them freely for now, this is a pivotal time in their life where you teach them they are heard and it’s important that they take care of themselves
we had a journal exchange where she wrote in her journal each evening and if she wanted me to read it she left it open in my room, is she didn’t then I respected her privacy. It’s really important that you keep the trust here and don’t read it if she doesn’t want you to as it’s shows again that she has autonomy and control
we did a poster each called ‘things that I can do to take care of myself’ and wrote all over it self care things we can do. Examples were meditation, fresh air, talking about feelings, eating well, laughing, cuddling, baking. Everyone’s will be different. It was a good exercise to brain storm and give focus to positive things we can do in our lives to keep well.
I shared with my daughter times when I was really struggling in my life, divorce, family deaths, and spoke about how I sought help and how it bettered my life. She might not be comfortable with seeking therapy and you should respect that but by sharing your own experience if you can, normalises difficult feelings and give hope that it will pass. I said often to her that all feelings should be acknowledged and to recognise that all feelings whatever they are never last forever. This gives hope for change.
look after yourself too! Not only is this essential for endurance but it also models how to address one’s needs and stay well
tbh at 16 I’d give her Snapchat along with a conversation about how this isn’t the solution but you can see it’s very important to her and you trust her to use it responsibly and the deal is she keeps talking to you about how it’s going and flags any issues it might present so you can work through it together, emphasis on that this isn’t a threat to take it away if it proves difficult.
wishing you both well, it’s heartbreaking to know your precious child feels this way xxx
