How do I cope with the isolation of command at sea?

The isolation of command has turned out heavier than you expected, and out there you have no one to share the weight with. That is an honest thing to admit, and it takes a certain strength to say it plainly. The loneliness of the role at sea is real, and it is one of the hardest parts no one prepares you for. The distance is partly the nature of command. The final responsibility sits with you, and that sets you apart from the crew by design. But being set apart in duty does not have to mean being cut off entirely from every human connection. Many in your position assume the role demands total silence, and that assumption is what turns solitude into something that crushes. Build a line to someone who understands, even across the distance. Another master, a mentor, a peer you can reach when you have signal or make port. Say one true thing to them about how the weight actually feels. You cannot hand off the responsibility, and you should not try. But sharing the human weight of it, with even one person, is how the isolation stops closing in.
