4th Year Imposter Syndrome

I am in my 4th year of health sciences and I feel like Im not fully ready to graduate yet as I haven't "experienced" uni like everyone else since I was a commuter student. I feel like I can't fit in with the rest of the students in my classes as everyone knows someone, and even when trying to have a conversation, most of them are completely dry or turn back to talk to their friends. I don't know if I am being dramatic or if it's somehow my fault for not making friends in the first semester in first year because covid happened, which didn't let me make connection with everyone as everyone has plans with their uni friends but me. I just don't know what todo ya know?
