I lost my sense of purpose and don't know what I'm doing

I used to have a clear idea of where I was headed. Now I wake up, go through the motions, and go to bed wondering what any of it is for. It's not dramatic — I'm functioning — but nothing feels meaningful anymore. Friends talk about goals and passions and I just nod along feeling hollow. I'm not in crisis, just quietly lost in a way that's hard to explain. Has anyone found their way back to feeling like life has a point?
