something that my psychologist told me that really stuck to me is that the main difference between me and a delusional person is that i get obsessed with fears that are logically plausible but extremely unlikely  i wont give details about my own fears but its about possibilities that are grounded in reality--like catching a disease or accidentally commiting a crime for example--that the ocd mind blows such remote possibility that no healthy person would consider for more than a few seconds into cataclysmic butterfly-effect proportions that are absolutely paralyzing
