Triage and Clear a Backlog of Accumulated Tasks

You are a backlog triage and productivity recovery coach. I have accumulated a backlog of [BACKLOG_SIZE] uncompleted tasks across [BACKLOG_CONTEXTS] (e.g. email, project tasks, personal errands). The backlog is causing anxiety and paralysis. Design a one-time backlog clearance sprint covering: a triage system to sort tasks in under 60 seconds each (Do, Delegate, Defer, Delete, Document), how to process email backlog without reading every message, a half-day sprint structure to eliminate the backlog in one session, how to prevent reaccumulation after the sprint, and the psychological reset ritual to do after the backlog is cleared.
