Threatening to kill & has my ss#

I posted this is a different forum. I'm not really sure where I should post. This is my story.

My neighbor and I used to be friends. I would take the kids to school and she would pick them up. Her and her live-in boyfriend are having problems and I have been trying to help the BOTH of them. She called his wireless provider and pretended (somehow) that she was him and got his passcode and printed off his records. The records do not show the incoming callers phone number and she got really upset. I had told her that I talked to him on the phone and she was ok with that as long as thats all it was. We'll she started having these ideas that he was cheating on her with me and got all mad. She went to my oldest childs school, armed with a gun, picked her up and told her that she was going to go home and kill me. Is their any crime in that at all? Being on school grounds with a gun, threating my life, anything?
Then the next day, she got my (soon to be ex)(we're seperated) husband to give her my social security number so that she could call my wireless provider and pretend like she was me and get my passcode. Which she did and printed off my phone records. She thought I was having an affair with her live-in boyfriend. The info she got did not help her at all. My question is, is that against the law to pretend like you are some one that you're not and get their personal information? Now she can open credit cards in my name and not pay them.
What can I do? My kids live in fear everyday that she is going to kill me or them. My oldest sleeps with knives in her room now(WHEN I can get her to sleep in there. All the kids sleep with me now. This all happened in September. A week ago I find out that she has told someone else she was going to kill me. And then today we had a slight confrontation where she would have done it if she had the neccessary tools with her.
I really really need some help here. Please, anyone with info please respond. We live in SC if that helps any

Have you tried getting a restraining order against her? As far as going to your child's school w/a gun, why didn't the school do anything? Or did they know? Did you contact them after it happened? You need to get all this in order with credible documents to keep a restraining order against her. Make sure you put your children on this order as well. And if you can prove your soon to be ex husband gave your ssn out, I would talk to a divorce attorney to see what you can do about that.
Whether or not you get an order, I would protect your home & children one way or another.

Thx for the reply. I just don't know if a restraining order would make her more angry and make it worse or if it would make her think I was terrified and then she would feel like she could taunt me. I just wish there was a way that I could prove to her that you can't go around doing that kind of stuff. The school didn't know that she had the gun. Which I never thought about contacting them. I dont know if they could do something or not.
As far as the ss# goes, he told me he gave it to her, but his story differs from her as to why and it still does not make it acceptable. She has the ability to ruin me now. She has already ruined my rep. She has told everyone in my hometown that she caught me and her boyfriend together and a bunch of other lies. So now everyone is looking at me like I'm trash. And I didn't do anything. She is a big drama queen. When things are boring she stirs up trouble. And at times, I do fear for my life. 2 days ago she tried to attack me at the local flea market in front of everybody. I am 5'1 130lbs and she is 6'0 275 lbs. So I do have reason to be scared. But I don't want her to know that. Why should I live in fear everyday and she live happily ever after. She lives directly across the street from me. Anyways, thanks for the response. Any more advice from yourself or others would be great.

It's not about you being afraid of her, it's about protecting your children. If something had happened to you by this psycho woman, 1- you have a restraining order & she would get jail time 2- you need to be there for your kids. I have four children & when I moved to this state 8 1/2 yrs. ago, I was the new girl in a small town. I always had men hitting up on me & really never cared for none of them, of course other women were pissy, but, there is no trying to convince them your not interested in any of these men. And believe it or not, to this day, I am still being talked about. You know, these people have nothing better to do, I was afraid at one point in time, not no more. A few years ago I started standing up for myself & of course I had a few words to a lady who called my mother a "B", she stood up after I introduced myself as the "B"....she was like 6 feet tall. Trust me I know where you are coming from in heighth wise, I am 5'2 135 lbs. I thought she was going to stomp me into the ground. But she got up and left.
I am not saying be stupid like I was, although I was protecting my mother, I'm just saying you shoudn't care what anyone has to say about you. Protect your children and yourself. Please check your private message for some additional info.

My kids are my life. If they dont have me, they dont have anything. I think about it alot. I dont want to imagine life with out them. I saw my private message and I responded. thanks

Your Welcome! Keep in touch.

Get a restarining order and then the next time she breaks it THROW HER IN JAIL - do it time and time again, as many times as you need to. And for gods sake tell the school she no longer has permission to pick up your kids
