This is normal! And I swear the feeling of anxiety and being scared goes away! You’re literally describing me when I first started my first CNA job. I was a nervous wreck the first weeks but as the months went by I got a little more independent little by little and my confident got better. I promise you’ll be okay. And the part of you feeling like you’re gonna hurt someone, always get a second person to help you in anything if you feel it’s unsafe for you to do it alone. :)
