stalking, an interesting topic.
About the girl, I know stalking can make one's life miserable, because when you are being stalked by a person, it means that something is wanted of you. Stalking, if not handled with caution can lead to not just suicide and depression but; rape, murder, theft etc. so please, stalking should be taken seriously and if you're being stalked you can report a case of stalking and harassment to the authorithies
