Skinny friend noticed I'm getting fatter..

I was at about 100 or 102. I am now at 108. I am only 5 ft so it shows. my Nexplanon does make me eat a lot and I just broke my ankle. I need to get in shape again. Just look at these differences... What some pasta, rice, peanut butter, nursing school stress, and overeating can do. I do lose and gain weight very fast, but do you have any tips

? Only reason I asked is because my friend who is a 00 told me I got fatter. ugh.
