Anxiety after eating, or something else??

I’m not exactly sure if the problem is from my anxiety and depression, but I always feel uncomfortable after I eat! After I eat I experience a strange head rush, like my head feels heavy. My ears get hot as well. And then my heart starts beating out of my chest. My head feels foggy and my vision become just slightly blurred as well. I saw the college nurse, she took some bloods tests and all came out ok, my blood sugar was slightly low though, and I had eaten and hour prior. She said that depression and anxiety is very tiring on the body and when we digest our body has to focus all it’s energy on digesting, so that might be why I feel this way. It also is way more bothersome during the time that I PMS. It stresses me out because I really do love eating and I want to be able to enjoy eating again! I’ve lost 20 pounds this semester and I haven’t been trying to! Any insight would be super helpful. Thanks! ❤️
