Skinny asf

Soo I’ve been struggling to gain some weight 🤦🏻‍♀️ ive been a little bit chubby when i was in 5th to 6th grade and i have been bullied a lot because i was chubby and all, so at the start of 7th grade i slowly reduced the amounts of food that im eating. But it wasn’t too little, it was just right. And now im 16 too skinny and ive been eating a lot since last year because honey im underweight already. I never was on diet! I just reduced my rice intake and every other food was still okay for me. All my clothes that couldnt fit me before well it fits on me now. I swear im eating and never skipped meals, and im always hungry tbh. But my problem is it just always makes my tummy bigger but nothing happens to my whole body, just my effin tummy. So it looks dum because im too skinny and my tummy looks fat. Any tips on how to gain weight proportionally? Haha not just on my tummy but also on my whole body?
