How do I let go and trust others to do the work?

You do it all yourself, because handing it over means trusting that someone else will do it right, and that trust does not come easily. Underneath is usually a real fear: that it will be done worse, or that if it goes wrong it lands on you. That fear is not foolish. But carrying everything yourself is not a solution to it. It is just a heavier, lonelier version of the same worry. Here is the trade you are actually making. By doing everything, you guarantee the work meets your standard, and you also guarantee that you are the ceiling on everything and that you will eventually break under the weight. Trust feels like the risk, but refusing to trust is its own, slower risk. And the only way anyone becomes trustworthy is by being trusted with something first. So start small enough that the fear stays quiet. Hand one real task to one person, something that matters a little but not enormously, and let them do it their way, not yours. It may not be done exactly as you would have. Watch what happens anyway. You are not just offloading work. You are learning, one task at a time, that the world does not fall apart when you loosen your grip.
