I'll start this post by saying that I don't know if she has BPD for sure, but I've known her for 2 years and I'm pretty sure that at the very least she shows several symptoms that look like BPD. I know that my post seems desperate, but I don't know what to do anymore.

Basically, she started seeing a girl a month ago or so. She has a rough home life and so does she. Lately she felt really empty and right now is basically trying to fill that void with her. I'm pretty sure they both like each other romantically, it's just that no one has made a move already.

What I'm really scared about is that, everytime she can't see her, she starts to feel like shit. Hitting herself, crying, wanting to cut herself (Even though she never did it nor do I think she would, considering the fact that she's scared of blood).

She herself said that she's basing her whole happiness on that one person and I don't know anymore what to do with her because my words don't reach her nor would I know how to stop it.

I of course told her it's wrong and that I would like her to do something else too and don't focus too much on just one girl, but I know that just telling her that is not going to change anything too.

Some of you are probably going to recommend therapy, but her family doesn't want her to engage in it. Anything else? Do I just really have to wait until she destroys herself?
