Also, a couple more statements about BPD I could agree with (sry if already mentioned in this thread :P)...

"Trying to define BPD is like staring into a lava lamp: what you see is constantly changing. The illness not only causes instability but symbolizes it." - from Stop Walking On Eggshells

Also, "A mental illness where a person cannot control their own emotions.

This means that you feel like **** for literally no reason..." - from Urban Dictionary
