Depressed Facebook Stalker Syndrome
When someone browses the Facebook photos of his/her "friends" because he/she's bored and finds them doing fun things. As a result, with each click or wall scroll he/she becomes increasingly convinced that he/she should be doing those things with those people, and he/she forgets that he/she is not an important part of any of their lives. After realizing the former statement, the stalker becomes depressed.
Last summer I had nothing to do because all of my real friends were away or had jobs, so instead I stayed inside all day and suffered from Depressed Facebook Stalker Syndrome because that cute asian girl from my art class kept uploading beach pics.
