My diet?

I'm a sophomore in high school. And I do not eat breakfast in the mornings before school, because I'm usually not hungry. I rarely eat lunch at school because the line is super long, and I just forget to, or am too lazy to pack my lunch. When I get home, I eat a lot. But I fill up very fast. I don't have any disorders or health issues. I'm 5'5'' and weigh 119lbs. But I feel like what I'm doing probably isn't healthy... Is this bad?
