Estoy en el fuego! Je suis sur le feu! Anyone know what the correct idiomatic expressions for this sentiment actually are?

P.S. Leah Dieterich’s ‘Idieoms’ (“poems made of literal translations of non-English idioms”) are uniformly beautiful.

Above: Case in point. So lovely!

P.P.S. Prioritaire, a sweet and very easy-to-understand (both emotionally and linguistically!) movie narrated in French, by the same multi-talented Dieterich (also of thx thx thx fame). I adore everything she does.
