Am i wrong for stress eating

Hey yall my grandfather 59m died 2 years ago now and I'm just remembering the story. I was 12 or 13 when it happend I'm a male BTW. The worst part is ut was April fools so I thought It was a joke until I saw the body I couldn't cry or talk all I could do is just stress eat. He was my mentor we used to watch star wars and code together before he died and got sick the day he died I didn't go to school so the day I went to school I kept eating. Idk bet I eat inorder to grieve. Anyway a person I talk to once In a while he comes up to me and says I should stop eating or you'll go from skinny to fat I have a fast metabolism. And I walk around everywhere I told him I also said to mind you're business you're 50 pounds more than I am. So aitah for eating to much when my grandpa died
