From what I read, being able to recognise your emotions and your feelings ( understanding those latter ones as the emotions associated with a thought), it’s very necessary to regulate your mood.
I’m finding troubles to read them in myself.
For example, I’m having problems to identify just now, if the emotion I’m feeling is sadness or emptiness.
Not mention that I’m also finding difficult to distinguish between an emotion and a feeling since they seem to feed each other.

Were you teach in therapy how to do it? Did it make a difference for you to regulate your mood swings?
Any insight is much appreciated!
