Anxiety about failure

Hi.

All my life I am having anxiety issues,Never went for consulting since it decreases once that phase completes but during that phase it feels like hell I cry often during those times I feel anxiety for failure,to come out of my comfort zone,to have a change in profession and also during exams.How to overcome this.Its not that I can't work harder I can but does not want to since I feel pressured thinking about the outcome in a very negative way and constantly worries about it
