Lacking body positivity lately...

While most people here on this app struggle with LOSING weight, I’m here struggling to GAIN. So many people ask me if I’m anorexic, have an eating disorder, and the truth is, I eat like a 200+ lb GUY. It just never seems to work. I drink ensure, I eat small, frequent meals, and yet I never quite creep over 100. Stuck feeling like I’m 12 years old, and I just turned 22 at a whopping 97 lbs. Not to mention the fact that I wear a size 32AA bra 🙄 I was born premature so I’ve always been rather small, but now a days I see people wearing tight jeans and their curves and their adorable chests and I’m like ‘whoops sorry I’m still seven’. 😅 It affects my period too, I probably get one like once in a blue moon. Any of you girls have any issues like weight gain, and found a secret to putting on a few pounds?
