When we talk about emotions and feelings, we often take these two words as synonyms. Emotions, however, are not the same as feelings. I wrote about it in the blog post: Just Move.
To make it easier, let me remind you: emotions are the body's reactions to external stimuli and feelings are caused by emotions. Let me also remind you that I am per contra of rejecting negative emotions. All emotions are physiological and not admitting to them is - my personal opinion - like denying that we are breathing. But just like breath can be regulated to some degree, we can also control our emotions. And I don't mean we shouldn't or should react when our blood is boiling, I mean: don't let that blood boil.
