i thought i was a natural "night owl" because of comments like yours... until i didn't have electricity. suddenly im up and down with the sun and feeling rested and stable instead of sleeping 4am to noon and feeling shitty and depressed. i won't argue that natural cycles vary by individual, but how many people are fucking themselves up like that assuming it's just natural for them, like i was? you went straight to feeling attacked and lashing out, maybe log off instead of arbitrarily deciding you know what's in your DNA and jumping up people's asses about it when they describe how it works for most people despite what they prefer to tell themselves. try logging off and sleeping when humans evolved to sleep, it might help with that extreme sensitivity.
