It's going to be really hard, actually pretty much impossible, to gain any noticeable weight in just 5 days. The best advice I can offer you is to just flaunt what you got! I feel you on the whole commenting on weight thing...I don't think it's right either, whether the person is underweight or overweight. But if people make comments, so what? They are probably just jealous anyway ;)
However, you are pretty underweight for your height. I'm glad to hear you don't starve yourself or anything, because that's definitely no good. Some people just have really fast metabolisms. Have you ever had your thyroid checked? It wouldn't hurt to bring it up to your Dr next time you go in...you could be hyperthyroid, which would cause you to have a hard time gaining weight. They check it with a simple blood test and if they find that you actually do have hyperthyroidism, it can be regulated with medications, no big deal.
It definitely wouldn't hurt you to gain some weight, espcially since it would make you feel better. Even like 5-10lbs. If you want to gain weight, I reccommend spacing your meals out into 5-6 smaller meals instead of a couple larger ones. You don't necessarily have to count calories. It might just drive you nuts lol. Try adding more calorie dense, but healthy, foods to your diet. Here's a list of some healthy weight-gain foods:
-peanut butter/nut butters
-2% or whole milk/yogurts
-more carbs (whole grain pastas, breads, bagels, rice, potatos/sweet potatos, etc)
-more protein (chicken breast, ground beef/turkey, fish, salmon, eggs, etc)
-dark chocolate (70% or higher)
-100% fruit juices or milk to drink instead of water
You could also get Ensure or Boost drinks at your grocery or drugstore. They taste kind of like milkshakes. Each 8oz bottle has 250 calories (350 for the Plus varieties), come in different flavors, and contain vitamins. I drank them when I was in the hospital for anorexia recovery and they helped me put on weight.
As far as exercise goes, try strength training at least 2-3X per week. Adding a bit of muscle weight is good and will help you fill out.
Good luck and remember to always be confident in the body you have!
