How to lose ten pounds?

So I'm a female, 5'5" and 135 pounds. I my goal is to be 120-125, but I can't seem to lose anymore weight. I don't drink soda at all and I drink lots of water. I don't eat fast foods, candy, or junk food. I exercise just by working in the stock room at my job lifting heavy boxes and such. I take a multivitamin and iron everyday(I'm anemic). I just don't see how I can lose more weight. I've started to read labels and eat foods that are low in fat, but what else should I avoid or add?
