I’ve upvoted your comment but I would disagree with saying “your clock is messed up”. The OP’s clock is fine and acting as it it’s ‘programmed’ to. What’s messed up is the way society places a higher value on the circadian rhythms of early-risers over those of night owls.
I recall hearing a theory that having individuals with differing circadian rhythms within the same social group provided an evolutionary advantage as not all members of the group would be asleep – and consequently vulnerable to external dangers – at the same time.
