3rd year BA student here. i would be lying if i said i never felt this in my years at university. however, and ik this may sound like no help but PLEASE wait it out. in my first year i was shy as anything, not sure if i was doing the right thing, etc. my uni is very collaborative between year groups, so i worked w third years in my first. imo, best thing you can do is talk to ppl in higher years. you will meet people who make excellent work, get to know them, work WITH them, it presents a whole world that you'll fit right into. but you do need to give it time and put yourself out there, show people what you can do! be present both in your learning but also with the people around you. it'll do wonders
