Feeling Like a Fraud in Tech—Anyone Else?

Hey everyone, I've been in the tech field for a few years now, but lately, I've been wrestling with this feeling of not belonging. I often read articles about new frameworks or optimizations and it makes me freeze up; I can't help but wonder, "How do they know so much?" I keep telling myself, "You got this," but then I look at my own code and feel like it's just plain bad. In meetings, I hear people using terms I barely understand, and instead of asking for clarification, I just nod along, which is exhausting. Sometimes I think I got lucky landing my job, and I'm terrified someone's going to realize I don't really know what I'm doing. I keep thinking that if I learn certain things, then I'll be more confident, but just when I think I've got it figured out, I find something new I don't know about. Is anyone else dealing with this feeling of being an imposter? How do you cope?
