Will my friend come back

I hope I'm in the right place.

Hi I had a good friend maybe even a girl friend that had been living with me for a couple weeks. I've known her for several years but this is the first time we have ever been this close. Her ex had kicked her out after they lost their home and she was in the process of fighting for her kids. Anyway she got were she thought her ex was bugging her phone and tracking her movements then she turned this theory toward me. After 2 days of her screaming these accusations at me and threatening to call the police saying i was beating her I had to get my sister in law to come over and help me get her out. I guess my question is after this episode that I assume was brought on by all the stress subsides will she realize that they were really delusions or will they remain as facts in her mind? She went to her mothers and I can't get past her to be able to talk to her. I miss her and am worried about her. Any advice would be greatly appreciated.
