I have an interest in depression too, interesting thread.
I have never suffered depression as far as I know. I used to go out with a depressed (and just majorly f*cked up) girl, who seemed to think I had depression too, but if this is true it can't have been very serious. Apart from her, I have a best friend whose girlfriend and sister have had depression. But more worrying to me is that my elder sister has it too.
She is amazingly intelligent and talented (not to mention, others have told me, plenty attractive) but has now dropped out of university twice because of her depression. She has been living at home for ages now, not doing very much, and is starting to seriously piss me (and everyone else) off. Every Sunday lunch (generally the only time the family is together) starts with a shouting match and ends with her crying and storming off. This usually results in Mum crying too. At random times in the day and night more shouting matches occur, after which she will typically run off to her boyfriends for a few days.
I am pretty sure my campaign to have her kicked out the house wasn't the best tactic, but it was very cathartic. Anybody have any better advice with how to cope with someone like that?
PS Just to clarify, she doesn't just argue, obviously there is the standard crazy-person list of things like knackering Dad's car by crashing it while drunk and so on. Too many to list (and frankly I think I repressing some of the worse ones)
