Change your phone number. Make all online profiles private (I thought that deleting my myspace and making a new one without my name would help, but no--MySpace decided to feature me on "cool, new people" when I did that). Let other people know someone is stalking you. Notify your job (if there is security at your job, be sure to tell them). Don't walk out to your car alone. If you can, file a police report (I tried this two years ago. A female cop over the phone told me she would file one for me, but when I got to the station, it was a male cop I dealt with, and he simply just told me to call them if he showed up at my house...one of the "good ol' boys", I guess). SAVE ANYTHING YOU CAN, for example--Voicemails, text messages, myspace/facebook messages, etc. Always be aware of your surroundings.
