usually it's some combo of those 4 primary emotions for me...

for example i'm soooo mad at my bf's best friend leaving me nasty vmails. so i start crying and screaming and going nuts.

then to calm myself down i try to figure out what i'm really mad about why im freaking out.

and it comes down to sense of injustice for sure, but also confusion and pain. that wasn't right what he did, i don't know why he did it, and it hurt like a kick in the guts.
