IMHO, you feel how you feel. I think as ACAs, we've spent so much of our lives denying, hiding, stuffing our feelings, that actually feeling is a strange, well, feeling! Lately I've had a lot of tears come up. My first instinct is to stuff them and hide them and gulp and blink and do anything I can not to cry. But there is something there that needs to be heard, experienced, expressed.
It is natural to have emotions. If you are feeling scared, then you are feeling scared. Are there actions you can take to help you feel less scared?
