What does this mean? (Ask.fm related)?

[Bridget]

I have received a threat on ask.fm saying (exactly) "Aww you little brat I know who you are and I will kill you" I don't think I have done anything wrong but people tend to dislike me fairly quickly. I think I am ADHD (I researched symptoms and stuff) and I'm kinda impulsive, interruptive (is that a word?) and hyper A LOT. My friends believe that I am and say it is apparent and I'm wondering if that's why people dislike me? I also have five girls in my class who truly hate me for no apparent reason and they are mean to me frequently including kicking my backpack and being rude to my face and on the internet. Why do you think they do this? I don't cut and I'm not suicidal and I will not ever be so I'm not in danger of that... Help.

Have you told adults about this? Believe it or not, adults can help you with bullies.
