(15m) have my first job tmrw, anxiety is killing me, what should I do?

technically not my first because its a summer job and ive had summer jobs before, im very nervous, i didn't want to do this job in the first place but my mom made me. I get there around 7 am and the length of days really just depend on the heat, im assuming my first week will be till around lunch or at latest like 3pm, but im nervous af, im also dreading waking up early. this is going to suck, theres also a shit ton of other ppl working there and I only know 1 friend in total, no idea what im gonna do
