Probably gonna get fired

I’m working seasonal at a new job, it’s a tourist location and we get so many customers every day. My first week i was under on my till and now three weeks later I’m over by a bit also. I know this is really bad. Anyone have any tips or any managers willing to give their point of view ? I feel uncomfortable sometimes at cashier but i have to deal with it I’m just a greeting because i really love this job and my new friends i made.
