I agree that you need to leave, most especially if you are in danger and she is violent towards you, but it just makes me sad for her. Im not saying its wrong cause it isnt, Im just thinking of how bad she feels inside, know she needs help but terrified of Drs so much so that she would rather self harm...and could be violent towards you and doing it in front of you to push you away. Im not sure thats the reason but its possible.
Personally I dont self harm in front of anyone nor would I and though I explode verbally, I dont become violent nor would I. But i do push people away screaming silently in my head "please dont leave" and increase the self harm and other desructive things when they leave. Its an abandonment thing, 'leave them before they can leave me', and Im just wondering if thats what she is doing.
Like i said though, i agree that your saftey is first. It just makes me sad for her as she's got to be in a lot of emotional pain.
Its possible that she has PTSD but it sounds very much like Borderline Personality Disorder with the self harm, non-regulated emotions etc. If you stay there longer it might be worth reading up on it. I have BPD and most BPDers arent violent to people, only to themselves, but its way possible that she has cormobility (more than one mental disorder) and its also possible that her "explosions" have turned violent. All of it is non-regulated extreme emotions. I feel all emotions in their most extreme form and that's why seroquel xr's slight deadening effect is good for me. My emotions are still more extreme than most but its lower than it used to be to give me more middle ground for them. That along with DBT has helped a ton to regulate them better.
If you stay there longer while trying to find a place, it may be worth talking to her about not all Drs are the same. Therapist's arent always Drs (mine isnt), that the friend's death were over 10 yrs ago and the knowledge of mental health is much better today. And id offer to go with her if thats possible for you because it is all due to fear.
I do fear for her once you leave. It isnt healthy for you so if nothing chances then leaving would be needed but that still leaves me in fear for her. If you can get her to go to a therapist then she has a running chance after you leave. Obviously you can just leave and that wouldnt be wrong, its just a thought.
Its all sad to me for both of you.
