111 pounds

I am 5'5 and 111 lbs. , according to the BMI index I am at 18.5 so I am at the lowest point before being too skinny. I feel as though I look to skinny. Should I gain weight or enjoy being thin?

Whatever you feel is right, thats what you should do.

If you like who you are, be yourself. You shouldn't be intimidated by what something else says. When you're hungry, eat. When you feel you're too skinny, maybe just gain weight and then turn it into muscle.Or whatever you want to do.

if you feel uncomfortable being the size you are then you could try eating pria bars or cliff bars. Something that would help you gain weight but isnt really fattening. Some people just have fast metabolism also, so eating more might not make a difference.
You arent unhealthy, so it really is just a question of whether or not you are a size that you like being.

dont try to get fat. just build more muscle but not to the extent where its gross. and my bmi is 17. sumthn but im 13 so im on the skinny side of the scale too. I dont really look skinny though. anywayz enuff about me :D just do whatever you feel is right but mainly if you want to get bigger, get more muscley

 
You have a BMI of 18.47.

BMI is equal to or less than 18.5 (Underweight)

A lean BMI can indicate that your weight maybe too low. You should consult your physician to determine if you should gain weight, as low body mass can decrease your body's immune system, which could lead to ilness such as disappearance of periods (women), bone loss, malnutrition and other conditions. The lower your BMI the greater these risks become.

I'd suggest that you try to gain a little weight. However, you should probably do it by eating AND exercise so that the gain is more muscle tone than fat. If you were to gain maybe 10 pounds you would still look good and be quite healthy.

follow your heart dont change yourself unless you're doing it for you, but skinny is not sexy, its always good to have some meat (not fat) on your bones.
