Is there a word or synonym for "turning inside out?"

I am trying to find the word for the act of turning oneself inside out, with respect more to showing one’s feelings on the outside instead of supressing it.

The closest words I can come up with are explode, expound, expand, express. Extricate? Is there a word that starts with Ex….? I can’t remember, it’s probably a word I learnt in childhood but for the life of me I cannot remember.

Thank you!
