Emotions SUCK!

Emotions suck. They are completely pointless. They do absolutely nothing and only cause a crap-load of grief that is really not necessary. Not to mention that emotions make people do stupid things. And forget things. Emotions make us want things and hate things and love things and fear things, and whatever else we people do. But emotions as we know them are just labels. Words we humans put on categories of ... (anything) that we don't know the name of. But really, who can say what an emotion really is? What defines happy or sad or incredulous? What defines a broken heart? What defines the difference between "like" and "love"? Is one more real than the other? If anyone had any answers, I'd love it if they'd tell me.
