Always hungry and unsure about cause...?

Okay so I'm 14 and ever since around November I've been getting really hungry. (it actually started after I got food poisoning) That sounds like a weird thing to be worried about but it's weird. I eat something and soon afterwards I get hungry again. I have anxiety and also my allergies have been bothering me. Websites have said this hunger could be anxiety, diabetes or something else lol it's just bothering me xD I doubt it's diabetes (although my mom IS hypoglycemic) anyone have any suggestions on what might be causing this/ suggestions on how to stop it. Sometimes I'll eat something and I won't be hungry until lunch and then I'll eat the same thing the next day and be hungry right after. Hahaha
