Feeling Overwhelmed in Grad School

I never thought I'd be one of those people who's overwhelmed by grad school. Here I am, drowning under papers and endless readings. Last night, I stayed up until 3 AM trying to finish an essay that was due this morning. It’s like no matter how hard I work, it just isn’t enough. Sometimes, when everyone around me seems so confident and capable, I feel like I’m the only one who can't handle this. Maybe someday I’ll find my footing, but for now, I just keep pretending everything is okay.
