Can I do it? Special night ahead

Anonymous
I have a big event that I really want to dress to impress for. Lately though I have been so stressed out and with that gained a couple of unfortunate pounds :( I have around 20 days to lose them again. I need to know if its possible. I really want to look good in a dress. If I keep my diet to about 1000 calories a day, go running 3-5 miles a day and drink plenty of water will this have a major effect on my look? currently 5'3 about 180lbs. I need to look good in a dress help!
