As far as I’m concerned, you'd better stay at home till it cured. Though stye is not a highly contagious disease, long time radiation from computer as well as lack of sleeping does not work for symptom and even make things worse. A warm compress is a good way to treat your stye. You can wet a cloth with hot water. Then place the warm compress on the affected eye for 5 to 10 minutes. You are supposed to do this for several times a day, it is normal to take about one to two week at most for the stye to disappear. Nevertheless, if it is really getting more and more serious, you'd better go for their help and accept the relative treatment in order to get a recovery.
