drama queen
An annoying bitch who always feels like every insignificant problem in her day is a disaster of Hurricane Katrina proportions. Anyone who so much as gives her the time of day is in for an endless session of hearing why her boyfriend is such an asshole or how she's fat because she can't wear size 0 jeans along with an allday crying marathon. 

If you value your sanity avoid these psychic vampires like the clap or you'll never have a minute's peace.
My ex girlfriend is such a drama queen.
