I'm at my wits end, so please be kind.
Basically, my dd has been nothing but trouble for the past couple of years.
When she was in yr 11 she constantly refused school for various reasons- she felt anxious, she'd fallen out with someone, she didn't like a certain teacher, every reason you could think of.
She managed to pass a couple of GCSEs, and got into college doing a course she wanted, as well as resitting her maths gcse.
Eventually she started skipping college as well, with all the excuses under the sun.
Shortly after starting college, she met a boy, who the whole family knew was bad news, she saw him for a few months, before she ended the relationship, admitting that he was abusive towards her, and also encouraged her to smoke weed.
When all this was happening, I made myself ill with worry, and did everything I could to get her to college, and try to stop her seeing this boy.
He ended up coming to our house, screaming abuse and spitting on my door, and the police were involved.
Fast forward a couple of months, she's still refusing to go to college, saying she feels scared in case he turns up there (the college have done everything they can to reassure her that she's safe there).
She won't get a job, she's done absolutely nothing since she left school last May.
I've worked with the college to help her, they've bent over backwards to help her.
She spends everyday on her phone on snapchat- talking to various boys, she was previously sending nude pictures of herself for money on snapchat 
She's also on a dating site called yubo, and I've seen some of the pics on her profile, they're awful .
She went off to meet someone today, not telling me who it is or where she's going- I'm sick with worry that she's seeing her ex boyfriend again.
She's horrible to me, calls me all sorts of names, she does nothing to help round the house, I clean her room and she messes it up again, it's a complete pigsty.
She's doing absolutely nothing with her life- she said she needs to think about what she wants to do at college as she didn't like the course she was doing.
Yes she has anxiety, but often uses it as an excuse to get out of things.
I also suffer with debilitating anxiety, but somehow still have to work and look after her and the other children.
I'm sorry if this is a little muddled, I'm a wreck, I have posted about her before, but not sure how to find my other thread or link it.
As an example of how vile she is to me- she borrowed money from her younger brother last week to get her nails done, and refused to pay him back, I told her she had to, and she called me a fucking cunt for going in her room to ask her to pay him back.
Last year when she was refusing to go to school (yr 11), we were arguing one morning about her refusal to go, she kept telling me to get out of her room, then threatened to "kick my cunt in" if I didn't get out.
Please please someone tell me what to do, I'm not sure how much more I can take
