Anxiety in this new career

this is for everyone who is new to dental assisting and people who have been in this career for awhile how did you push yourself to try and do the job/training even if you were scared,anxious or nervous? i just finished my program recently I'm certified but we had no actual hands on training I've applied to jobs and emailed/called local offices for shadowing or training opportunities i haven't heard back yet but i know once i do i have to push myself to do it and try but I'm the type of person that's so scared of failure and being embarrassed and not being good enough due to personal reasons and how life was growing up i just don't know how to push myself to try and ignore the anxiety i feel like a failure already because i have no faith in myself and that sucks so much.

So i'm writing on here just for stories/advice to help me because i know i'm not the only one feeling like this or that has felt like this
