Is it normal that i feel better when i have food in my stomach?

I'm a 21 year old female, but this girl likes to eat. If I don't get some food in my stomach every few hours, then I start to feel crappy. It's the same thing when I don't drink water often enough throughout the day. I just feel better when I have food in my belly because I don't like to feel it empty. Whenever I mention that my stomach feels weird or hurts, my mom always tells me I will feel better when I get some food in my belly. She is right though because I do feel so much better when I fill myself up. Actually, if my stomach bulges out a little bit after I finish eating, then I feel even more satisfied.
