If I Manage My Eating Will My Heartburn Go Away And Not Turn Into Cancer?

I am now eating more plain foods. I am only 12 but is scared that i have a higher risk of cancer when i grow up. It is hard for me to feel relaxed due to my depression. Is there a cure for depression and heartburn? I’ve heard that vinegar can help. I am scared to eat fried or greasy foods, even eating big portions makes me feel uncomfortable. Don’t scare me too much with you answer please. thanks. oh and should I drink a shot of vinegar? Does heartburn comeback when I’m older and increase a risk of cancer?
I am on Zantac and Heartburn Antacid
thanks.
