Constant whining

Idk if it's related to teething or what, but my baby has been a constant whiner for the past several days. I don't think she even knows what she wants. It's psychological torture akin to the sleep deprivation in newborn days. I try to remind myself that the poor thing is unhappy or uncomfortable for some reason and this is her only way to communicate, but that only works for like one minute.

Any tips for coping- either practical tips or change my attitude tips?
