What’s a good way to quit my one month job

I’m currently a full time student and I have a part time job where they pay good and it isn’t much work. to keep things short I just want to quit, ive worked for bath and body works prior and i genuinely loved it more because of the people in there, everyone was sweet. I also want to get a full time job back at home since this is part time. I’m just scared to quit because the people scare me and I’m scared to let anyone down tbh. please send advice that could ease nerves or simply on how to tell my manager.
