starting a new job in LAUNDRY at a nursing home? please help!!?

So i just got a job working in laundry part time where i have to hang personal clothing items to residents that want their laundry cleaned by the facility. im so nervous because ive never used a washer and dryer that big before (I DONT KNOW HOW TO OPERATE IT) and i just really want to do a good job! i know he will help show me what to do, but it takes me two tries to get something so i’m worrying! i’m supposed to deliver clothes to each room from a rack and make sure they have their name on their clothes in their closet. i’m so scared ive never done anything like this in my life! ANYBODY DONE THIS JOB BEFORE OR CAN GIVE ME ANY TIPS ON WHAT TO EXPECT WITH THIS JOB? I start in 2 days and i cant sleep im so nervous! help!!
