Is it normal to constantly have anxiety attacks and feeling dread before going into work?

I’ve (f25) been at my position for nearly 10 months now. This is my first “real” job out of college. The company has put me in a position where I’m doing the job of two people and they aren’t looking to hire another person. I’m capable of making mistakes (I have already made a few and this is scary as I hold responsibility of people’s lives - I’m a nurse at a clinic but I still feel new. I don’t have hospital experience and there are things I simply don’t know. But it’s just me there). I am constantly overwhelmed, and I wouldn’t dare to do this - but I have thought things like how I am better off not being here anymore because I can’t function to do my work properly at work.

My weekends go by incredibly fast because I’m constantly dreading Monday. And then when Monday comes it’s like I hate myself all over again.

Is this a normal feeling?
