Self harm and depression in teens

[Madoldlady]

My daughter has always been a ray of sunshine, she's clever, articulate, kind, funny, hard working, she has a solid group of friends who (in the main part) are all pretty good kids. She did really well in her GCSE's and is now in college. Today is her 17th birthday.
She came home from this evening prattling on about the b-day cake I sent in and what a success it was and laughing, we got to talking and she started to cry, she told me she was depressed, she said she had strong feelings of inferiority and loneliness, she confessed to self harming. eventually she showed my her arms. I can not even begin to explain how tough that was.
We talked for a while, and planned to go and see GP on Monday and she's promised no more razor action. After some time talking and hugging, she washed her face and got ready to go to her Dad's for the weekend. When he arrived it was like normal, she laughed, joked, prattled on, made plans for the weekend all totally normally.
What can I do to help her? I'm in such shock, and so very very worried.

Thanks in advance of any help.

liveoutloud...going through family and emotional trauma is hell enough without blaming yourself for something you 'may' have done earlier in your child's life. Have no pearls of wisdom, but as a parent of an older teen recently diagnosed with bipolar disorder, after several hellish months, am sending you hugs m'dear. Don't be too hard on yourself...kids this age always seem to remember the crappy stuff we may have said or done and not the context. Take care of yourself too x

Hi my daughter who's 14 has a boyfriend who ive just found out is a self harmer. On looking through my daughters photos on her iPad i have opened a can of worms :( photos of my daughter cutting her own legs and arms in appropriate photos of her taken by him messages to support groups from her looking for help for him as well as messages between her and others discussing the best way to help this kid? I almost found messages where she has discussed her weight and how unhappy she is but she has gone on and lied saying me and her nan have been calling her horrible things like a fat bitch and telling her to diet? I would never hurt my child in this way. What do I do??

I just wanted to say I self harmed a lot when I was a teenager as a way of dealing with emotional pain. I was often very depressed and considered killing myself multiple times but I got through it. I am now a mum with a great career. Although this doesn't help you now dealing with this now I just wanted you to know there is a way through what seems like hell now.

It's so hard to know why to do for the best :( my daughter is telling her bf lies about how we treat her and I'm worried hell self harm as in his messages he says how worried he is for her? She posts pics and says she has body issues and can't eat whilst I know other wise as ive seen her just this weekend in a bikini and she's always taking pics of herself and eats me out of house and home? She was a loving girl before she met him.? Now I get grunts n sly looks I think they're toxic together and ive grounded my daughter with no internet access but I can't keep her in forever?! Arghhhhh x
