Free, my eldest daughter went through this in middle school. She was being bullied at school and obviously we had home issues. I was so shocked, I could not even believe it.
However, she went to weekly counseling and within a relatively short time had passed through it. She later admitted that there was another girl who did it so she tried it too. It was a call for help. In looking back, she says she cannot believe she did that and that she would never do so again.
You are right not to panic. One thing her T did tell us is that eating disorders go hand in hand w/cutting many times, and he just advised me to look out for it. It did not happen w/her, but I just thought I would mention it to you.
Tight hugs momma. You are doing great.
