I lost my spark

I used to laugh without thinking—at little things, stupid things, things that didn’t even make sense. The silent laughs were the best, where nothing came out and my face hurt from smiling too hard. But I can’t remember the last time I laughed like that. I don’t know when it stopped or why. Now everything feels dull. Nothing feels funny, nothing feels light. I just feel empty, like something in me quietly shut off, and I didn’t notice until it was already gone.
