I have a bad appetite so I imagine people cheering me on so I eat more.
Does that help you eat more?
It rarely does, but I don't know what else to do.
Not having an appetite isn't normal and could be a sign of medical or psychological issue such as an eating disorder. You may see better results if you find a doctor to help you out.
I feel fine mentally, I just don't have time to eat.
There is always time to eat. You can still go to a doctor, they can help you create a healthy eating schedule for yourself.
