I do have anxiety eating fatty foods only because of my severe acid reflux and possible gallbladder disease but nothing like you are describing. Are you absolutely sure that it is anxiety, some other health issue(s)?
What do you mean by tripping yourself out like you're having a heart attack? Like you feel chest pain and some arm pain? If so, that could be heartburn or some other health issue (not trying to scare you, sorry!
) I only suggest this because you say it is triggered by fried and/or fatty food which is what triggers my above issues with chest pain, arm pain, back pain, and/or some stomach issues as well. But the body shaking, that is a bit odd.
If it's totally not heartburn and you are sure it is anxiety then I agree with veggiedaze
