<unk>  is the excessive fear of infinity and the uncountable, causing discomfort and sometimes panic attacks from thoughts of the infinity. It normally starts in adolescence, but in some rare cases, it can start before then. From Greek άπειρος (ápeiros) "infinite, boundless" and φόβος (phóbos) "fear". It may be caused by existential dread about eternal life after death. This fear is often connected with thanatophobia (fear of dying) since many sufferers would believe that eternity follows life, especially learning that afterlife would never end.
