Every single event has a cause. Things do not just occur randomly, they develop and something creates the occurrence of that particular thing. Does water just occur on the kitchen floor? Does the poster just occur to be pinned on the wall? Does the writing just occur on the paper? No. Every event, every effect has a cause. In science it is not until we can understand the cause that we can know they why, how, when, what and who; I guess the same goes for psychology and the psychological state of any being. One does not occur to be anxious one day, something causes it; whether that is because a chemical is depleting or an event from ones childhood is up for discovery. Now, maybe this is why I find it so challenging to challenge my anxiety, because I am not sure of the cause of it. If I am not sure of the cause of it, I cannot accept the cause and work on challenging the effect. I became aware of the cause of my depression and am slowly tackling and challenging it. My anxiety? I’m still lost.
