I'm under-qualified for my job and scared that everyone will find out.
I feel like I don't know what I am doing and I am way over my head. I am scared of everyone finding out I can't do anything and being fired.
For context, I'm 19 and have a career in IT. I had a 3 months-long internship. I knew the manager that agreed to take me on the team through a volunteering program. I did okay then, but they didn't give me all that much stuff to do in the first place. After the end of my internship, my manager said that, should I ever wish to be hired permanently, she'll be glad to have me.
Well, I wanted to. And she told me my colleagues were happy to hear I've come back permanently as well. I am a Junior dev now. They've made me responsible for a very complicated system - but it's nothing I've ever worked with before. I was not familiar with anything of its current 'tech stack'. I'm seeing everything for the first time. I am so so lost.
It's been another 3 months. Now whenever my team lead asks me questions related to my work, I barely know what to answer. I am struggling a lot with my daily tasks - I've managed to do them so far. But it feels like it's becoming harder and harder to hide what I don't know. I feel so...slow.
I am really scared of not being able to manage it, and getting fired - I love and need my job.
