Infected insect bite

Infected insect bite may27 2014.... It has been a week and it still looks like this ???? I do not know what to do.....

I have been covering it up with concealer so it wouldn't look like this at work..... I don't know how long i can keep on doing it.. Sometimes i would just like to plaster it with band aid and be done with it but that'll just bring more questions from people....... I have just been treating it with peroxide and antibiotic..... I am soooo screwed......
