Stop indulging in delusions. They are destroying your health and wrecking your nerves. Instead, begin to live with your reality, as it is.
Work to correct your immediate problems. Leave tomorrow alone – it is beyond your grasp. As for people whom you imagine may do you harm – if they aren’t bothering you at present, don’t embitter yourself with obsessive thoughts about them.
Limit yourself to dealing only with the present time, the present place, and the people you are now involved with.
