Need to gain weight!!!!

Grace

Okay so I’m 4’11 and I weigh only 89 lbs 😩 I really want to gain weight and I feel like I eat a lot ! But then again there will be a day where I have absolutely no appetite :( what should I do? I literally eat everything but no weight gain, it just fluctuates up and down. I’m trying to get to 95 lbs at least. I just feel so scrawny and I’m tired of being told to eat something as a joke🙄
