Trigger warning: overeating

Lately I feel so bad after I eat. Eating as a chubby woman is stressful. I don’t get why I feel so bad about the way I eat just because I’m chubby, when there is skinny women who eat the same things I do freely. Whether it’s me obsessing over how much I ate or how what I ate effected me, its too much. I have a problem I guess. I overeat until my stomach hurts. I do it every time and I know I should stop eating. There’s a voice in my head that says stop eating and I ignore it all the time. I’m just so hungry and I enjoy eating so much. Sometimes I feel its the only thing during the day that makes me happy.
This has caused me to gain some weight of course. I also have developed Gastrointestinal Reflux Disease. I have constant acid reflux. Not only that but, my esophagus and stomach hurt often from how much I eat or because of what I ate. But for some reason I’m just so hungry. I know some of it is emotional eating. But I also have a hormonal disorder that causes me to gain weight easily while having trouble to lose that weight. This condition is called PCOS.
I genuinely want a better relationship with food but I don’t know how. The healthy choice is there but I chose the one that will fill my stomach the most. Lately I’ve tried to add more fiber and protein into my diet so I don’t feel the need to eat so much. And this has helped tremendously. I am also trying to listen to the voice that tells me to stop eating because I’m full. My body isn’t telling me that to hurt me or deprive me. I need to listen to my body more. I think one day I will figure it out one day but in the process I am going to try not to be mean to myself and to accept myself.
(If anyone has any tips to help with an undying appetite please comment haha.)
