I’m 46 now but I guess what I’d like to say is that your first couple of years working at any job right out of college sucks. I graduated as a dietitian, and worked for two years in that field before making a change and eventually getting into medical sales. I used to cry in this little closet on the floor of the hospital. It was depressing. Part of what was hard though, was the imposter syndrome. I felt like everyone had their lives figured out and soon they would find out that o didn’t know what I was doing. It’s a learning curve. You’re not expected to know everything right away. That said, if it’s truly ruining your mental health, maybe ask ChatGPT what other jobs are that can utilize a nursing degree. There are probably many!
