How do I leave this job well without burning bridges?

You can plan an exit the way you plan a trip. Dates, tasks, a tidy handoff. But planning is not doing. The part that trips you is a conversation — the moment you must say the true thing to a real person who may not like it. So you delay. You wait for a better week, a calmer mood, a sign that it will go smoothly. There is no such sign. You are not stuck because the plan is unclear. You are stuck because you want them to feel good about your leaving, and that is not yours to control. A bridge burns from vagueness and delay, not from honesty. Say the plain thing, on a date you chose, and do your fair share of the handoff. That is the whole task. Everything else — their reaction, their opinion of you, the story they tell later — belongs to them.
