No word for it

I know this is not done, but right now I feel like a mute with no words, yet who is overwhelmed with torrents of feelings that it is difficult to repress, to keep quiet, so I borrow words of others - I came across the following passage while reading a novel and it expresses my sentiments in the raw tormenting manner I feel

“Have you ever wanted something, Sidonie, so badly that it almost maddened you?” he finally said. “Something that made you itch from the inside out, that kept you sitting on the edge of your bed every night with your head in your hands and your heart in your throat? Something you almost, almost had—and then you lost it so suddenly it made you ache with…with what, I don’t know. Frustration? Thwarted desire? No. I have no word for it.”
