Hi  :)r.Me2,
"Should I convey she is suffering from emotional dysregulation? " . Not a good idea to use a label that is not well understood by her. Your guess is right, this will result in a blow-up. In general the path "abstract understanding of emotional problem--->seeking help" is not likely to succeed. Lack of self reflection is often part of the condition which makes it hard to recognize for her that there is something off... .The crux of the matter is that this illness is beyond reason. It is however not beyond our ability to influence as we can focus on emotions and on limits/boundaries. We believe we live in a rationale world and are not so used to use emotions and boundaries but it can be quite powerful.
Having said this there is nothing wrong in validation i.e. acknowledging and feeding back to her that she is "totally upset", "angry beyond pale", ... .It can help in the short term and over time it can help increasing the ability to reason about her emotions. For more on validation see the workshop section or LESSONS.
She has not gotten any better and her attacks are getting stronger and stronger. Dizziness and numbness continue and it has been a couple of weeks already.
Escalating aggressive behavior is a real concern and it is important that you protect yourself effectively from abuse. Depending on the level you may need to put an emergency escape plan in place. Lack of solid boundaries (boundaries that are alone under your control) is often a factor enabling her to escalate. It may be worth working through some boundary
workshops like
Examples of boundaries and then post concrete questions on the
Staying Board and discuss your boundary plans.
