MIL showed up slamming on my door after getting my address from landlord.. grounds for restraining order?

Location: North Carolina

Been having ongoing conflict with my MIL for over a year. It escalated to the point where I blocked her number back in March, but my husband didn’t block her (I thought he had).

Yesterday, she texted multiple family members and my husband asking for our address. None of them gave it to her, but she then went to our landlord’s office, pressured the elderly husband (who has cognitive issues), and got our address from him.

She then showed up at my home and slammed on my door for four straight minutes while I was home alone with my infant. I hid in the kitchen with my baby until she left because I was terrified.

She has a history of harassment, boundary violations, and showing up uninvited, but this is the first time I’ve felt genuinely unsafe. My landlords have since banned her from the property and said they will press charges for trespassing if she returns.

I did not call the police in the moment because I froze, but now I am considering seeking a restraining order.

My questions:
-Does this behavior meet the threshold for a restraining order in North Carolina?
-Would her showing up uninvited and harassing me, plus the landlord’s statement, be enough evidence?
-Should I file a police report retroactively for documentation even though I didn’t call at the time?

Any advice is appreciated.
