Something that organized your life is gone. Maybe it was a relationship, a role, a project, a belief. Whatever it was, it gave your days a direction and your choices a context. Without it, the ordinary things, getting up, deciding what to do, explaining yourself to yourself, feel harder than they should. You are not in acute crisis. You are in something quieter and in some ways harder: the absence of a reason to move.
Three thinkers on the Consilium roster have thought carefully about this specific problem.

Baldwin: you have to discover it, not wait for it
James Baldwin was not a philosopher of consolation. He did not believe that meaning arrived on its own or that suffering had a guaranteed upside. What he did believe was that honest confrontation with reality, including its hardest parts, was the only way to eventually find something real to stand on. The people in his writing who make it through are not the ones who are spared. They are the ones who stop pretending.
Not everything that is faced can be changed, but nothing can be changed until it is faced.
Baldwin would ask whether you have actually faced what happened, or whether you are managing it, narrating it at a slight distance, keeping yourself from the full weight of the loss. He thought that the avoidance of hard truths was itself a kind of trap, and that the path through was always through. Not because suffering is instructive in some tidy way, but because what is real only becomes navigable when you stop pretending it is something else.

Russell: expand the circle of what you care about
Bertrand Russell lived through enormous personal losses, including the collapse of several relationships and a number of his deepest beliefs. What he found, and wrote about directly, was that the antidote to a lost source of meaning was not finding a replacement for the exact same thing, but rather expanding the scope of what you cared about. The person who cares only about one thing is always vulnerable to losing everything when that one thing goes.
The good life is one inspired by love and guided by knowledge.
Russell would point you outward. Not to distract yourself from the loss, but to acknowledge that your capacity to care is larger than the particular object that organized it. The question is whether you are willing to let some of that capacity attach to something new, something you did not plan on caring about, before you know whether it will sustain you.

Confucius: return to practice
Confucius was less interested in meaning as an interior state than as something produced by practice and relationship. You do not wait to feel purposeful and then act. You act, and purpose sometimes arrives through the acting. He placed particular emphasis on ritual and role: the small structured practices of daily life that connect you to something larger than yourself, even when the feeling of connection is absent.
The man who moves a mountain begins by carrying away small stones.
Confucius would not tell you to wait until you feel ready. He would tell you to identify the smallest possible practice that gestures toward something you care about, and begin it, today, without expecting it to feel meaningful immediately. The feeling follows the action. It does not precede it.
Where they locate the problem differently
Baldwin would say: you may still be avoiding the full weight of what happened. Face it directly, not because it helps immediately, but because avoidance makes the path longer.
Russell would say: your capacity for meaning is larger than the specific thing you lost. But you have to be willing to let it attach to something new, before you know if that attachment will hold.
Confucius would say: begin a practice, however small. The feeling of purpose rarely arrives before the action. Start moving and see what the motion teaches you.
What none of them would tell you
None of them would tell you this is fast. They would also not tell you that something equivalent is waiting around the corner. What they would each say, in their different ways, is that the response to the loss of purpose is not passive. It involves a kind of deliberate reorientation, whether inward, outward, or through action, and that reorientation is something you have to do, not something that happens to you.
