I read Brainlock and found the four-step method useful. However, I sometimes can't figure out whether my fear is real or just OCD. If it's just OCD, I can use the method to deal with it. But what if it's not? What if it's something I SHOULD worry about? I fear that I would mistake a real fear as OCD and cause terrible consequence. So my question is, how can you tell it is really OCD instead of legitimate worries?
