That was me in the first few months after I had to replace the senior dev when he took a better job. I was only junior for like 5 months prior to this, I also lied about having 2 years of experience in the interview and the team misunderstood my quick learning with expertise. At the end they thought I was good enough for the position but I was freaking out because I was lacking a lot of experience, I still took it because the raise was huge. I couldn't sleep well for months while I was trying my best to learn how to do my job.
