Dd has always been very emotional, and can turn from lovely to violently angry in a second. One minute she is friendly and the next she is horribly abusive. She lies about everything and shows no remorse for how she behaves. She is very sensitive and we have to make huge allowances for her in normal everyday things. She uses screens as a way of hiding from the world, and from things she has to do and is a massive procrastinator. She is very academic, and comes across as shy and sweet in public and no one can believe she treats us the way she does. It was a real struggle to get her to school through the sixth form, and she lied a lot to her teachers about her work. She was diagnosed with a mild sleep disorder, and for a long time I thought she would be better if she just got a good night's sleep, but now I think it is worse than that.
I know she has self-harmed and had suicidal thoughts but she won't talk about why, and she refused to keep going to the counsellor we found for her. She did go to the Gp off her own bat, but they just recommended Steps to Well-being and she won't pursue that. She is extremely closed about her feelings, and refuses to talk about her outbursts except to blame everybody else. I think she has soured every family holiday we have ever had.
Lockdown was not going too badly but a couple of weeks ago she flipped for no reason we could see and started attacking her brothers physically, throwing things and breaking plates. She is refusing to have anything to do them or even to eat with us as a family, although she will act fairly normally when they are not around. I thought she had calmed down but then yesterday she tipped a plate of food over her brother just for walking into the kitchen where she was to get a snack. She says she wants them to die, and threatens to hurt them. I feel sick at the thought of the damage growing up with her has done to them, and sick at the thought that she might hurt herself because I love her so much.
Over the years I have googled everything from anxiety to autism to sociopathy but nothing quite fit. Now I'm pretty sure she has EUPD as she fits about 90% of the criteria but I have no idea how to get her help because she won't even entertain the idea of talking to a doctor or counsellor. DH wants to set down some clear boundaries (if she doesn't sit down with to eat she'll have to cook her own food, if she is violent again she will have to leave the house) but I think tough love has never worked with her before so it won't work now. I'm also really hesitant to suggest she has EUPD because I think she will twist that and turn what we say against us.
We are basically looking forward to her going to university in the autumn so we can live a life not tiptoeing on eggshells. It feels horrible to say it but I cannot wait for her to leave. And then I worry that she will crash and burn at university and hurt herself or worse. Or that she will have to come home and I'm not sure I can cope any more with her living in the house permanently (I can just about cope with holidays, I think.)
Does anyone have any recommendations of books to read about how to help her, and manage our family life? Or websites? If you have EUPD did you accept a diagnosis or were you in denial for a long time? What is the best way to stop her being so horrible to us whilst loving her and looking after her?
Tl;dr: I'd love any advice from anyone with experience for DD who I'm pretty sure has EUPD.
