Finding "the one"

[Ironside]

That's how scientists define these things though. For most psychological disorders, one of the requirements for someone to be diagnosed with it is "significantly interferes with quality of life" or "causes distress" in a way that is not expected during normal development.

......... Q.E.D.

Seriously, you never had or know someone who have been "generally distressed" because they've fallen in love with someone they would never consider to have a relationship with? Or to put it short "I love him/her, but I just don't like him/her".
