Erotomania

Erotomania is a delusional disorder in which a person believes another person is in love with them when in reality they are not. The person of focus is frequently a famous person or a person above the status of the erotomaniac who is unaware the person loves them or even exists at all. Erotomania can lead to harassment of the person who is the object of the attention. Some stalkers of celebrities have erotomania - they believe the famous person is in love with them and communicating their feelings to them through their media. This sometimes leads to stalking or other dangerous behaviors.
