How the author describes anxiety？

“thinking sometimes leads you up to a locked door. you are denied entry, however hard you knock there seems to be some insurmountable barrier, a refusal to give you what you are seeking. yet you sense something is there. you feel as you are in a state of suspended animation; you are wandering around in the dark. all you have are unanswered or half-answered questions, doubts, uncertainties and contradic-
tions. you are like a person who suspects there is something gravely wrong with their health and is awaiting the results of medical tests. the temptation to anxiety or fear is over-
whelming. anxiety is diffused fear, for the object of it is not known clearly or visibly. if you are in a jungle and see a tiger coming towards you, you are afraid; if there is no tiger and you still feel afraid, you are suffering from anxiety.”
