apologies in advance if this post is rambling and complicated but not sure how to edit as it's all relevant. Currently struggling with very angry 17yr old dd who has been secretive and closed off for much of her childhood. In the past four years she has been through averagely worrying teenage stuff but some more worrying. Solitary drinking, smoking weed, spending what seems like days in her room, not wanting to mix with family, cutting herself occasionally. When she was little we were very close (tell myself this over and over like a mantra that will stop my heart from breaking). She dropped out of sixth form after only 3 months even tho she is very bright and after months of begging her to tell me what was upsetting her so much (she refused) and spending months trying to guess and going through lists addressed to the back of her head saying "if its this (gay/drugs/depression/someone abusing her/phobias and anything else i could think of) we can handle it together and i will love and support you no matter what it is only for her to go mad one day and start screaming at me that it was me that was the problem and i had stopped showing her i loved her and she just wanted to be my friend. I have caused all her problems, etc etc. Was devastated and cant actually match up my experience with what she has said. All this is made way worse by dh who has no boundaries and never corrects her even when she is screaming that i am a f c** in front of her little brother. she has also thrown stuff at me and is totally rude and domineering. DH lost his job last summer and the two of them now skulk around the house together all day and he swallows everything she says and repeats it to me as if gospel. With her bad behaviour he just writes it off as being a teenager. Have notice that my son, who has been angelic, is now starting to copy his dad and sisters attitude and vocab towards me. Friends have told me that it is an abusive situation but i am terrified of losing my relationship with my son. Help!
