Sometimes, it can be very helpful to live in an illusion - to keep yourself so distracted by daydreams and fanciful wishes that you don't have to deal with unpleasant thoughts. So if you are having troubling thoughts, it might be okay today to just pretend everything is just fine. Think good thoughts and if there are uncertain situations, just pretend that you know the outcome for certain - and the outcome is good. Fake it until you make it, because you will make it eventually. Have hope!
They must be able to read minds because this is spot on! :)
