I constantly feel fat when I eat 😔

Bri

I’m very skinny, so much so that I’m underweight. I barely eat as it is not, because I don’t want to just because I don’t need much to feel full. When i do get cravings, which my cravings are like a whole bowl of hamburger helper rather than a little portion, I feel so fat afterwards and I regret ever eating it. I constantly feel bloated even when i eat the tiniest bit. It’s making me want to cut down on eating. I eat between 1,200 and 1,500 calories a day. Why do I feel like this all the time?

I’m 17, 5’7 and 107 lbs if anyone was wondering
