In real life and online. One was an ex-boyfriend who totally melted down after we broke up. It went on for two years. He stopped when I threatened to tell his parents (can you believe that?) The other was a creep from grad school who just started following me home one day. When the semester was over, he disappeared.

It's so funny you asked this Q right now. I have a colleague who's beginning to email me constantly about unnecessary things, always in a bullying and antagonistic way. She's been asked repeatedly not to contact me, but she does it anyway. It reminds me of my former stalkers. She's self-diagnosed with a 100 different disorders, so she always blames he bad behavior on "symptoms."
