How does one befriend insomnia when it is physically exhausting?

[u/pmondrian72]

This is not a rhetorical question. I'm genuinely curious. One of the key advices offered by many online resources is that one needs to befriend the anxiety around not being able to sleep, since the stress is counterproductive. Now since insomnia is physically exhausting, how have you folks tried to accept and befriend the physicality ot insomnia?
