This one girl in my school who I've known fo about half a year used to be nice and happy but now shes having mood swings and shes rejecting everyone and being really emo. Now shes stalking me and won't leave me alone! She keeps on trying to get my attention and won't just leave me alone even though I ignore. I think she has a crush me buts I really really don't like her at all since she went emo and had mood swings. What should I do just keep on ignoring her or get my point across that I don't like her?

well...dont tell her straight out u dont like her and stuff cuz that'll prolly make her more emo.....explain that shes changed, and you dont see her as the same person..but say it like niice....

tell her that you don't like her because of her mood swings. if you're worried about her, then tell her you maybe would if she cleaned up her act.

Tell her that she's being really annoying but don't be mean. This will either make her even more emo because she tried to impress you and only made things worse or make her go back to how she used to be because she will do anything and really likes you.

I would stay away from her. If she asks you a question then answer, but for the most part stay away. Or, maybe you should just talk to her and see what her problem is. Then maybe she will leave you alone.

get your point across

Well, she might be going through puberty or something. Tell her you don't understand why she has changed, and try to be nice to her. Maybe then she will be a little bit happier.

NETHER!
If shes having emotional problems then she might think you are the shoulder she needs to cry on. This 'stalking' as you call it, could be her last cry for help. In Private i would talk to her.
I would simply ask how shes doing and why she seems to be 'following' you.
She might not even notice that she is!
