Usually, numb is a state of despair, for me. Sinking feeling in the gut, heart loudly beating and a little faster. Different than an anxiety palpitation. I, usually alternate, situation dependant between calm, some joy, some anger, some sadness. Irritated comes when physically tired, and I am fluctuating between thinking about life, money, love, politics and focusing on family and I feel unable to breathe. Anger, tends to be situation dependant, may get a bit shaky in my hands, as I tense up, lip gets a little sore, biting has been age old self soother, biting my own lip, i must disclaim, if I am in psychotherapy work throughs, self work, actually, if something triggers my past upsets, I feel sick to my stomach and recognize it's an old wound.

I know sadness, from the tears.
I know happiness from the smiles.
Joy is longer lasting than happiness, i think? Joy is something I work on..

Think that's the usual suspects of emotional physiological reactions I can personally think of, at this moment. ..
