Got my pap results back, I'm confused

So I just got the call from my doctors office with my lab results from my pap. The nurse said that I have abnormal cells, but she says it's nothing to worry about. She said I could get it from being stressed or not eating healthy and not sleeping (all of which I do a lot), they're going to see me in a year to test me again. Should I be worried? Obviously I'm going to try to be healthier so the cells will clear but I feel like the doctors are taking this too lightly. They aren't even doing any further testing unless I still have abnormal cells in a year. Idk I'm just freaked because I feel like I should be but all the medical people seem so calm about it.
