Quick French Check

I'm writing a small thank-you to my French teacher but it has to be at or under 25 words. (She taught my class Sartre, which explains the reference in the beginning.) How can I keep the general gist of this without getting above 25 words? Thanks in advance, lovely linguaphiles! Here it is-

Jean-Paul Sartre a dit que l’enfer, c’est les autres. Selon moi, l'enfer est la vie sans le français. Merci d’avoir me donné une vie pleine de français !

Edit- Thanks for the help, I've got what I needed! You guys are the best. :)
