Take care !!

I went through the same thing. I was always skinny growing up. now im 5'1 and 117. if you wanna be average, then around 120. below average would be around 115

dont feel too bad, im 5'8 and weigh 112 pounds, I cant seem to put weight on no matter what, I've been like this for 5-6 years now

It really depends on your body type and your genetics (mom and dad). I have a friend who was slim and beautiful. She plays soccer a lot. But her parents are stocky. So at 16 she's started to 'spread'. But as long as you're physically active and in good shape, just don't pig out, be fit, a few extra pounds aren't big deal.
My friend is no longer an hourglass figure, but she's in shape and can kick butt. You can't change your body type, you can change your body fitness. You go, girl.

I'm 5'2 and I weigh 117. I personally would like to be between 110-115 but my main goal is to decrease in fat and increase in muscle.

I think you are at the perfect weight for your height. If I were you I wouldn't gain weight but I definitly wouldn't not lose an ounce.
