The injury took your season, not your purpose. Rehab can be holy ground.

An injury takes something specific and definite, and the loss deserves to be named rather than immediately reframed. What it does not do is remove your reasons for being here, though it will feel that way when the thing you organized your year around disappears. The slower work of recovery is not empty time, and it tends to teach things the season would not have.

Grieve the season properly first. Then treat rehab as the current work rather than a wait, and be useful to the team from where you are.
