I think my teenage son (18) is self harming, but I can't be sure. I have seen wounds and scars on his lower arms (just above the wrist) which, when I mentioned them, he said were nothing and hastily changed the subject. It's taken me a while to realise that it may be self harm. This year I have never seen him in a anything short sleeved.
I really don't know how to talk to him about it, if that would be the right thing.
Please could somebody give me some advice.
Thank you
