What is going on 🤨

OK SO, this past 6 months maybe I've been experiencing hunger pangs RIGHT After I eat and it happens every time a couple times in a row but it usually goes away in acouple days but it's not stopping these past couple days. My stomach feels empty and growls right after I eat. I've also noticed my anxiety is just random. Like, I'll be doing nothing like watching TV and I'll start getting anxious and start shaking. Does anyone know what it could be?
