Feelings vs Emoitions?

Is there a difference between the 2? Sometimes when I do my thought work it seems there is a part of my brain which just pours out childish Emoitions vs other Feeelings which seem more sensible. This must be primitive brain vs frontal cortex?
So sometimes I want to use an E rather than F in my models. Please advise your thoughts re this.
